First HP: Partfrac gives crazy answers

I am recently taken a first HP to replace my TI-Nspire CASE and in almost every way I used it so far, I think it is a much better device.  However, there is one thing that really frustrates me.  The frac command part even if I am sure that the answer is correct, that it is simply ridiculous to work with.

I try to get partial fractions of (z)/((z-0.5)(z-0.8)) and the first gives me an answer that I can't easily type here since it is medium long.

My TI gives a real simple (40 / (3 (5z-4)))-(10 / (3 (2z-1)))

Is it possible to do the HP to put things in simpler terms?  I tried to simplify and it goes nothing.

Hello on4now4,

I am not a number first, but a hp 50g. I saw in your example, you use 0.5 or 0.8 numbers. The first and hp 50g operating system have a similar concept. If you type in numbers with the decimal sign calculators switch to another mode and then CASE (hp 50g will automatically use the way of reconciliation, the first maybe the home mode), where these functioning as partfrac do not work as expected. Try your example with fractions 1/2 instead of 0.5 and 4/5 instead of 0.8. This can work.

Awesome!  It does not work!  A little annoying that I have to enter as a fraction, but I can live with this solution.

    I'm having the same problem on my 5 s. Siri often setincludes my voice when you ask a question and so gives me the wrong information. for example, ask Siri to call or text someone in my contacts. It started when I updated to iOS 9.3.5. Tried all sorts of things to heal a few weeks ago, but nothing helped. I dropped. It is particularly intense in the car.

    Will update to iOS by the end of the month. I want to see what else shakes with this version, until I do it.

  • How do I give the answers of my modem in a VI after each command that I send it so that I can see and document his actions?

    Hello colleagues LabVIEW'ers!

    I created a program that will interview a modem which is connected to the serial port on my pc.  I use the VISA starting functions by the serial port set it up and then I plugged into the function WRITE, then the BYTES to the PORT, then the READ function and finally the CLOSE function.  The problem statement is as follows:

    ~ How do they give answers of my modem in the VI after each command, I send it so I can see his actions and ultimately to report query out of it?

    Furthermore, I don't know if my commands syntax is correct.  Otherwise, I used a program called cygwin interface and a single command, I used is "ssh root@"ipaddress"[enter] This brings me to my modem connection control.  The cygwin command syntax would work with my labVIEW VI? If not, then how can I know what the command syntax to use to query my modem to LabVIEW?

    Additional information

    Modem - modem Satellite 'Evolution '.

    Version of LabVIEW - Professional 8.6.1

    Method of communication - Serial Port

    I appreciate all the assistance of those to receive, and I also hope that responses to this question are many who come through it.

    It seems that you have some apples and oranges here. Cygwin is a Linux for Windows environment. It gives you a bit of Linux look-and-feel in Windows. SSH is a secure, shell, which is a network protocol, not RS - 232. The serial port is a different interface. It may or may not have the same commands that you use on ssh - the manual will tell you that.

    Regarding the serial interface that you want to do, it looks like you want to just do something like what did the old LVTerm . You can give that VI a test to see if it does what you want.

  • First Pro CC gives an error "Could not create image buffer" and crashing after installing a videocard GeForce GTX 1070.

    Hi all

    I recently installed a GeForce GTX 1070 video card and drivers current in my bench mounted, very happy for the potential break in the rendering and playback (I was using previously a very old ASUS Radeon HD 7850). I had nothing else problems since.

    When I first tried a project of creation of opening, audio refused to play (speakers, headphones, everything...) I looked at the volume mixer while playing through the timeline and no audio only showed upward). Everything seemed fine. I closed, cleared the cache, opened the first, this time hold Alt while doing so to reset the preferences. Open very well, audio read back fine, that only now first was blocked indefinitely the generation of PEK files for a short audio clip in the project.

    After a long bit of troubleshooting in the speakers, I went ahead and did a complete uninstall of Premiere Pro and After Effects, then reinstalled both programs to their current versions (2015.4 and 2015.3, respectively). No more problems of generation PEK, but something much worse. Now, whenever I try to change the CUDA acceleration enabled, I can maybe five minutes absolute performance first until I get an error "Could not create image buffer", warning of notifications of Windows that your computer is low on memory, and finally, a complete crash where the screen goes black, flickers a couple times, then stays black for good with only the mouse cursor appears on the screen.

    The images that I'm editing is all images Go Pro, no effects applied. I am doing this for a client and need ready in a week, but the constant crashing makes them difficult to work around. I can more or less run by changing the acceleration of software only, display options but it is much slower and the memory is still eaten up like crazy (if I place the open Task Manager and start to scrub through the timeline I can watch the memory usage get up to 95% in 20 seconds approximately). Reading suffers as a result once the RAM is full until almost full.

    Technical specifications

    First Pro CC 2015.4 (latest version)

    It is worth noting that, with my old dusty Radeon GPU, I was able to edit these clips with ease. No reading, no problem of image buffer. I do not see my RAM never go above 60% usage, when I got this card is installed.

    Also worth noting, that the first, I have noticed absolutely no problems, and the video card itself seems to work very well. I can play MGSV at max settings with perfect reading, as well as other graphics intensive games.

    Any help?

    It's been almost a week and I had zero problems. First Pro CC 2015.2 works like a dream! I'll go ahead and mark this thread closed.

    For those just tuning, I was able to find a solution by uninstalling the Premiere Pro and After Effects, and then reinstall them back to last known stable on my bench (Premiere Pro 2015.2 and after 2015.2 effects). So far, running these versions has been very good, even with active CUDA acceleration.

    The only downside is that all the projects I've done in Premiere Pro version 2015.4 should be re-edited from scratch. But I've had absolutely zero problems using the program, which is a relief. Hope Adobe fixes this problem whenever 2015.5 is out!

    I have Photoshop elements 11 installed, but Premiere Elements will not install because of the problem of installation of shared technologies. I'd like suggestions on how to solve the problem. I tried installing several times.

    205EdMLewis

    On what computer operating system is your first items 11 running? For now, I'll assume Windows 7, 8 or 8.1 64bits. You install the program from

    disc Setup or installation files?

    Error Shared Technologies is an old story that affects several versions of Premiere Elements on several different operating systems. My encounters with this error

    used for the program involved installation disc.

    There are many remedies at home. One that worked for me lately and consistent was the deactivation of the OOBE folder located

    Local disk C

    Program Files (x 86)

    and in the folder Adobe is the OOBE you disable by changing the name of the folder in OOBE to OLDOOBE.

    Hello world

    I'm in a real jam: I worked on a film of long hours with special effects and many layers of audio, and just recently it froze PP CS5 upward. It seemed to be gradual, I added more clips, now when I open my project, it will just freeze. He seemed to have a lot worse after that I made my film in pp I have been using 1920 x 1080 clips directly from my digital SLR .mov and put them in PP. I have no idea what the reason is for this purpose; What is a random bug in CS5? What is a codec problem? My image is too big for my computer (i7, 8 GB of RAM + very low end GPU)? Do I need a better computer to work with images this big?

  • Spellchecker drives me crazy

    Is it possible to disable the spell 'feature' correction in Skype for Windows 8, or at the very least make it actually work? I have Windows 8 with the Spanish (Spain) by default entry/method/etc. language implemented in the Windows options, but SkypeW8 points out almost every word as bad. Even more infuriatingly, it will be "correct" a few words quite right for BAD alternatives. For example if I write "hecho" ('fact', 'done') it will automatically turn it into 'echo' ('for', 'expel'), which is absurd in the context.

    I tried to check the language settings in Windows 8, they are fine and no other application gives me bad. I tried to disable the automatic spelling correction first and then even the spell checking in Windows 8 Metro settings (settings of laptop-> General-> spelling) nothing works, SkypeW8 simply ignored my settings. I tried to add a language English (UK) to see if the spell checker got right English... the same problem did surface, with no word never acknowledged as correct.

    If you please, that gives crazy me and I can't use same Skype for desktop PC because I have a unrelated problem that won't let me write all text messages (people here, it's because of some 'Youtube MP3 downloader' but I don't have such a program). Is it possible to work the spell or least make him shut up and do not correct me (fake) in my native language?

  • Outlook Express 6, doing crazy things ~

    I am running Windows XP (which I have no time for her disc) as well as IE 6. My outlook express does things that are crazy. First of all, when I answered or even send e-mail, it happens to my Outbox and it seems that it will not send and I get an error, but no code error not listed for me to research. But I think that it is sent, because people are responding to it. Also, when I get emails in my Inbox, I can't delete them or move them, he said only that a mistake occurred. I don't know how to fix OE. I upgraded to IE 6, thought that would fix it and it didn't. I also installed IE 8 and still no help. Any suggestions?

    You have corruption of dbx files.

    Spend most of your messages out of the Inbox and move any message you want to save out deleted items and sent items and then close OE.

    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.

    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.

    With OE closed, find and remove:

    Deleted items.dbx
    Sent Items.dbx
    Outbox.dbx

    New files will be created automatically when you open OE.

    Compact all folders as described below.

    To avoid this in the future:

    Do not archive mail in the receipt or sent items box.  Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.

    Information on the maximum size of the .dbx files that are used by Outlook Express:
    http://support.Microsoft.com/?kbid=903095

    After you're done, followed by compacting your folders manually while working * off * and do it often.

    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.

    Disable e-mail in your anti-virus program.  It is a redundant layer of protection that devours the processors and causes a multitude of problems such as time-outs and account setting changes. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:

    Hello CherCastle Cherreegirl,

    This is a public forum, you don't talk to anyone who works for Microsoft, quite ordinary people who enjoy helping others with their respective problems. You should not include any e-mail address or the password (they obviously have been removed for security reasons) in any forum. Imagine the headache that you could have caused if your details had not been withdrawn? You included your e-mail address and the password that would allow anyone who has access to these forums to hack your account. Anyone could also change your password, making it impossible for you to access your account.

  • Satellite L750 - implementation of Recovery Wizard when first turned on

    Hello world

    I recently bought a L750 and when I first turned on it, came a window asking me to set up the re product Recovery Menu Toshiba Recovery Wizard. Now, this is all new to me, so I didn't really know what it was because there were no instructions, so I answered a few questions then I cancelled out of the task, in which case my answers were wrong. Can anyone help me re - establish, answer the questions correctly and also where to find a second time to implement?

    The first 3 questions that I answered were:

    1. Please select a type of operating system to continue - 64-bit version of Windows 7 32-bit version or Windows 7?

    2. Please select a process: default factory software recovery (recovery of State out-of-box) OR wipe the hard drive (delete all data and the paartitions on your hard drive)?

    3 Please select a method of factory default software recovery: recovery of State out-of-box (System Recovery Options are included) OR recover without changing the disk partitions hard OR on a custom size partition?
    Then I canceled here.

    Thank you very much
    SC ("laptop computer Novice")

    Hi Shell73,

    > 1 . Please select a type of operating system to continue - 64-bit version of Windows 7 32-bit version or Windows 7?
    I would choose the 64-bit version because only 64 bit version supports 4 GB or more. Even you have t n 4 GB I would choose this version because you can very easy upgrade of RAM and 4 GB of RAM is recommended for Windows 7.
    If you don t have very old programs they need 16 bit you can use the 64-bit version.

    For example, I use Windows 7 64 bit on my two laptops. I put the 32-bit version of t need more because most of the applications are already compatible 64-bit.

    > 2. Please select a process: default factory software recovery (recovery of State out-of-box) OR wipe the hard drive (delete all data and the paartitions on your hard drive)?
    You must select restore to out of the box to this facility and the installation of recovery. As its name suggests, erase the hard drive, it will remove the HARD drive whole and nothing more. So, in the end, you have a removed HDD without software Yes, a bit useless (in my opinion).

    > 3. Please select a method of factory default software recovery: recovery of State out-of-box (System Recovery Options are included) OR recover without changing the disk partitions hard OR on a custom size partition?
    Choose the recovery to out of box state too. This will restore normal factory with all the drivers and tools. After that, you are also able to use the HDD recovery partition size option and that can also be changed after the installation of recovery.

    If you have any other questions, just after again! :)
