• fix variable (first emulator)

  I have an equation that I entered the first emulator and want to solve for a variable. I am able to work when I put in values for each variable and leave a vacuum. It solves for the fine missing variable in this case. I want to do is solve the equation for a variable when none of the variables have a value. I expect it would be re - arrange the equation for the variable I scream as it does on my ti89 titanium. Instead I just get a set of brackets in the {} the answer.

  The equation is:

  diffImpedance = 2 * ((80/√relativeEr) * (ln ((1.9*(2*heightSmaller+cuThickness))/(0.8*diffTrace+cuThickness)))*(1-heightSmaller/(4*heightLarger)))*(1-0.374*e^((-2.9*(diffSpace/heightOverall))))

  I put in all the variables as variables user and then store the equation in E0.

  Can I do: solve (E0, diffSpace)

  and the answer I get are the media. I tried it with more basic formulas, and it is the same thing. I'm doing something wrong?

  Thank you

  It must be remembered that A - Z are predefined, numeric variables. This means that if you use them, you pull the value. The first, the symbolic and digital are not mixed together. It's just like if you went through and stored all your variabels from A to Z on the 89 0. It will pull the values to use and you don't have simple variables.

  Press the CASE, type your expression — notice that variable screen where are tiny - and then press ENTER. You get the symbolic solution.

  Solve ((3*x^2) = (5 * y * 4 ^(z-2)), z)

  If you try to make symbolic, exact calculations, then you must use the screen CASE. If you are only numbers and want nothing symbolic, HOME is the place to be.

• Just me, or is the 50g low in solving differential equations?

  Hi all

  I used Ti-89 s widely in the past, as well as the Ti-NSpire CX CASE and now the 50 g for about 1.5 years. I love some aspects of the 50g (sensation of keys, ease of unit, RPN conversion), but I can't help but notice some areas where it reallllly hangs out of the competition.

  It is an example that I really noticed recently in solving differential equations. So far, several examples I've tried (all immediately resolved by my Ti - 89 and Nspire CX CASE), the 50g smothered on each.

  A very simple example: solve y "= - 9.8, with boundary conditions y (0) = 2.9 and y'(0) = 3.8.  This can be solved by hand in about one minute, but the 50g can't do. If I input ['d1d1Y (X) =-9.8' ' Y (0) = 2.9 ' ' d1Y (0) = 3.8 '] in level 2 on the stack, then 'Y' on a level and then run desolve, it returns "Error: Undefined result.

  I missing something here, or is - this really unable to resolve such a differential equation based? I thought that advanced and 'better' mathematical capacity HP CASE was meant to be one of the reasons why it takes precedence over offers from Ti, but I must say, so far I do not see that.

  Josh

  Hello!

  Try with the exact numbers:

  ["d1d1Y (X) =-49/5 ' ' Y (0) = 29/10 ' ' d1Y (0) = 19/5 '"]

  « Y »

  DESOLVE

  (after SIMPLIFICATION) You'll get years:

  {Y (X) =-(49*X^2-38*X-29)/10}

• Algebraic manipulations of solutions to differential equations

  Hi, guys

  I found the general solution of the differential equation y "-3 t = 1 using the command DESOLVE. I did it manually first and the answer I got was: 1/2 t ^ 3 + 1/2 t ^ 2 + C1t + C2; However, when I do with the calculator that I get is: (2cC0 + t * cC1 2 + t ^ 3 + t ^ 2) / 2.  I tried everything in the ALG menu to get rid of the 2 in the denominator. Nothing has worked.  I'm in Exact, symbolic mode.  Am I missing something?

• V26 freezing the first time I open it to start the computer

  Since v26 Firefox crashes every time I use it for the first time after starting my computer. It starts fine, but as soon as I enter the first page I want to visit, she stalls. It reacts only after 1 or 2 minutes when it allows me to assign the task of windows 7 manager. After that, I don't have to kill the process or anything, it's just back to normal. If I close the program and restart then no problem.

  My specs:
  Dell XPS L501X
  Intel i3 2.4 GHz m370
  3 GB RAM
  Windows 7 Home Premium 64-bit

  Thanks for any help!

  You should maybe wait a little longer after Windows starts to give your security software enough time so that it starts well and initialize.

  It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• Lack of controls at the first HP

  I know that HP Premium is not an HP 50 G upgrade, but in the absence of better information on the plans of HP, everyone is looking to the first as the new flagship of HP Calculator.  It is reasonable to infer that first HP includes all the commands that are available in the HP 50 g?

  I am looking for the following 2 commands: ZFACTOR and DARCY. They are not in the catalogue of the first HP and are not mentioned in the User Guide. They are available at all?

  Thank you!

  > is - this reasonable to infer that first HP includes all the commands that are available in the HP 50 g?

  N ° and the 50g has no orders or ability first. Basically, these sepecific very specialized type of field controls that are remnants of the 48 series or earlier is not a priority. Especially since the vast majority are so darned easy to do as a user program because they are basically just a simple function that gets evaluated. Another good example is the F0λ function.

  Neither of those two you mention are in the system.

  Note that this does not mean they will never be added, but first is defintiely not marketed to the same users that (again) after so many years has found the 48 series absolutely perfect for them.

• Satellite A300-1RZ - stucks Windows 7 upgrade on the first step of the installation

  Hi all

  I'm Italian, I an A300 Satellite with Vista Home Premium I paid 30 euros for the free upgrade to Windows 7, which reached my House yesterday. I got 2 DVD:
  -1 to 'prepare' my phone: * TOSHIBA UPGRADE DVD *.
  -1 upgrade operating system: * WINDOWS 7 HOME PREMIUM UPGRADE DVD *.

  + The first step: + use the first DVD: all right, "the system is ready to install Windows 7, insert the second dvd. When I insert the other, I accept the license and after that, the first step of the installation: * "check system compatibility."
  * These steps is my problem.*

  I reworded more than 10 times the praxis but it blocks at this stage, I left the laptop at this stage, throughout the night, but today morning she was always there, no progress, it is clear that there is a problem, but I do not understand if it depends on my cell phone or on the DVD.

  I tried to boot the laptop with Windows 7 DVD inside, start the system by the DVD, but it ask me to format the partition where are the files of vista and is not an upgrade. I bought an upgrade just do not remove previous programs and do not format the first partition of the drive of my laptop.

  How do, which can, I turn to?
  Does anyone have the same problem?
  Does anyone know to escape?

  Hi a Dread

  That s strange because I didn't have a problem with my Toshiba upgrade disk. Everything worked fine! :)

  I put t know if you read this, but here's an update statement step by step:

  As you can read before the upgrade, you need to remove some programs if they are installed on your computer.

• Video quality of the first transformer TF201 ASUS

  I searched through the support network and can't seem to find a solution to the issue I'm having. So here:

  I'm running a first processor ASUS TF201, updated to the most recent version of the ICS (4.0.3).

  Version of the camera is TF201 - 0 x 9900

  Kernel is 2.6.39.4 - 00003-g12de84f

  Build number is IML74K. US_epad - 9.4.2.21 - 20120323

  I installed Skype for Android today (May 5, 2012) since the game of Google. It does not show an available update after installation.

  I am able to use Skype, audio/video... video calls (front and rear cameras) and audio work (using the loose term). Latency is less than 1 sec, but audio and video are synchronized, is acceptable. The problem is that the video quality is EXTREMELY poor, but only when using Skype. There no visible difference in video quality when going from the front to the rear camera... which is strange given the large difference in the qualities of the two cameras, there should be at least SOME difference in quality.

  I also Webcam installed on my first IP and webcam7 installed on my desktop, the video quality is remarkable when using of IP Webcam/webcam7 to test cameras.

  Is there a fix for video quality on the first? I see that other people report a 'green' screen with ICS, but I don't have this problem.

  In the images below, the first is the front camera, the second the camera back. In the two images, the magnified image is the premium, is the smallest of my office.

  Please notify. Thank you.

  

  Good news! With the new update of Skype, the issue seems to be fixed. Thanks Skype! Now I can enjoy video skyping of good quality.

• The first Installation fails after first Boot of the Satellite L750

  Hello.

  I turned on my brand-new Satellite L750 - 04K 010 for the first time tonight (bought new) and start going through the initial setup process for Windows 7 Home Premium. The installation must "Installing devices" and then hung up without activity for about 2 hours, how I decided to restart.

  Then I kept getting the error windows installation has failed and would then need to restart the installation process. The computer will restart but kept coming up with the same error and the loop would continue even once.

  I have not received the installation discs.

  I tried to press F8 to see if the computer repair would work but only gave options to repair the system to a previous state. No Toshiba option was available.

  Help!

  Thanking you in advance,

  Greg

  It's pretty stupid situation now.
  If there is no way to launch the installation of recovery once again I recommend your dealer and ask for help. With other words, ask for the replacement of the laptop.

  What you can also do is to contact the nearest Toshiba service provider and explain the situation. I put t know what they can do for you, but I imagine that you will get a DVD of recovery for the installation of the OS.

  Of course I n don't know what the right solution, but I don't see another option for you.

• Trigger on the first attempt

   I'd like some help / advice on my LabView program (attached) please. In the VI, the MyVoltageTask_1 is configured as a voltage signal corresponding to a pressure change inside an enclosed cylinder. The signal is transmitted to the BNC 2110 DAQ board / PCI 6133 DAQ card via a differential pressure transducer. 
  
  Ideally, the program should trigger as soon as I let air into the cylinder and start acquiring data, and stop as soon as its done. However, LabView does not trigger when I let the air into the  cylinder on the first attempt, but if I exhaust the air and let it in again a second time, the program triggers and I can see a graph of the pressure trace. Please let me know if there is something I should / could change in the program to have the program trigger on the first attempt. Thanks!
  

  Have you try to change the slope falling upward? I begin to take a look at shipping the first examples. "" "Open Finder for example of OR and go to hardware input and output" DAQmx "analog measures" voltage. Take a look to the example called "Acq Cont & chart voltage-Int Clk - Analog Start.vi ' I contains the basic structure of what you're trying to reach.

• I have problems with the installer of Windows and Windows Update, and the solutions that I found for the two each rely on the other broken system to fix the first.

  I use a laptop HP Pavilion dv4-1220us with Windows Vista Home Premium Service Pack 1, a 64-bit operating system, and I have problems with Windows Update and Windows Installer. When I try to install programs, I get the following, or substantially similar message without the error code:

  "Error 1719. The Windows Installer Service could not be accessed. This can occur if Windows Installer is not installed properly. Contact your support team. »

  So I tried to download Windows Installer 4.5 and install it. When I try to start the installation, it always hangs on the first step, "Initializing Installation."

  After searching for a solution to this problem, I found that Windows Update may have a solution. So I downloaded the 64 bit version and got a file named 'file Windows6. 0-KB942288-v2 - x 64. I tried to run this file. He opened a box that said, in order "Prepare for Installation", "Full Preparation", and finally "Searching for Updates ', before you open a second box, which reads" click OK to install the following Windows software update: fix for Windows (KB942288). I clicked on OK in this box, which opened another box, which says at the top "updates are installed" and in a smaller section, "initializing for Installation................... »

  However, no matter how long it works, it never gets past "Setup initialization."... »

  So I tried to run Windows Update in Control Panel. He ran for a while, before giving a message saying "to check the updates, you must first install an update for Windows Update." I clicked on the button that says "install now". He has flashed, a moment, "download and installation of updates' before you go to the"check for Updates"and then he brought back the exact same upward ' to check updates, you must first install an update for Windows Update" message as before. I clicked install now once again, only to go into the exact same loop. After about four times in a loop, I gave up on it.

  So I tried to install Windows Installer 3.1v2, which took a while before saying "not enough memory is available to process this command." and the abandonment of the installation.

  So, I tried to download a program from 'Mr. Fix - it' of Microsoft. It downloaded fine and then failed on installation, because of the same Setup error I received initially.

  Finally, I tried to restart my computer and each solution is represented. Then I clean my computer and each solution is represented.

  In conclusion, the mistakes that I have in Windows Update and Windows Installer cordoned off each other, as the mistakes of each program are based on the other program to be repaired. I'm at my wit's end here. My computer works fine without one, except that I can't install new programs. I can access the internet fine, access files fine, all my scans have developed own... I don't really know what is happening. Can someone help me with this?
