# First HP: HP first Simplification

Hello! I was wondering is there a setting where the calculator will give me the answer simplified without pressing me the button to simplify? This is my second day with the calculator.

Yes, this is a CASE.  Press SHIFT CASE (settings), and then set the option to "Simplify" (line 4) to 'Maximum '.  Please note that some features deliberately ignore this parameter, for example, heat, for obvious reasons.

DISCLAIMER: I do not work for HP. I'm a happy user of HP Calculator.

Need help here some Labview... I'm stuck...

No need to...

Step 1 - Take a 1 d array with 4 index example: 0.153, 121, 249

Step 2 - convert the elements of the array in their 0 hexadecimal equivalent, 99, 79, F9

Step 3 - concatenate the array index 09979F9

Step 4 - convert the hexadecimal string to a decimal 10058233

Any suggestions?

Thank you

OK, much simpler (at the bottom). A first simplification would be to get rid of 'snacking' (Center). I don't know why you're doing it (above).

All outputs are the same.

Of course, the way the question was asked was a little difficult, describing a complicated four steps procedure when a step is really necessary.

(In the grand scheme of things, there will be complications such as the byte order.)

Yes, catalogued is powerful, but extremely stupid at the same time:

In a first approximation, it doesn't change the bits of memory resembles them differently.

• First HP Calculator: basic use

It is my first graphic calculaot, so forgive me ignorance please.

When I go into the menu of CASES and I immediately want to simplify an equation or expression, how can I get the simplify() upward on the screen? (The only way I can make it work's first press a number as 1 in order to activate the cursor in the box, and then press BACKSPACE and press the increase).

How do I type an opening parenthesis, or a SINGLE closing paren without having to use () and then removing the extra parenthesis, I want? Too simplified example, if I type 2 + 2 and then decide to go back and put 2 + 2 in parentheses. I have to go to start, press (), then remove the supplement), then go to the end and press () and remove the extra (.)

How can I evaluate simple equations like x 8 = 16 so that x = 2? Now when I press ALPHA 8 (time) x, SHIFT (period) = 2 and press to enter. It rewrites only 8 * x = 2 on the screen. I'm expecting a x = 2 in response.

How to simplify (c ^ 3d ^ 5) ^ 2 * (cd ^ 3) ^ 3, then he gives me the right answer rather than rewrite the expression and then give me the right answer? (Right of reply: c ^ 9 ^ 19)

How can I make the proot() function returns accurate values? For example, proot (2y ^ 2 + 7y + 6) should return positive 3 and 4 positive, no - 2, and -1.5.

The trick is to first press the space key.  However, it is usually best to simply type the expression first of all, press ENTER, and then simplify the press.  In this way the unedited original expression is in the history so that you can tap it and re - use.

Method 1: Shift Vars (characters), then tap the bracket you want.

Method 2: (shift return) back for an opening parenthesis;  cursor - right back, for a closing parenthesis ().

Type this: solve (8 * x = 16)

Suggestion: Tap box tool, the CASES tab, solve, and then explore this menu by highlighting one of the Solve funstions and press the help key.  There are a lot of powerful options it.

How to simplify (c ^ 3d ^ 5) ^ 2 * (cd ^ 3) ^ 3, then he gives me the right answer rather than rewrite the expression and then give me the right answer? (Right of reply: c ^ 9 ^ 19)

First of all, to avoid the "implicit multiplication.  Since variables can have more than one letter, the first cannot know you mean c * d when you type cd.  He thinks you mean a variable called "cd".

Your example should be typed as (c ^ 3 * d ^ 5) ^ 2 * (c * d ^ 3) ^ 3.  Prime simplifies correctly as.

How can I make the proot() function returns accurate values? For example, proot (2y ^ 2 + 7y + 6) should return positive 3 and 4 positive, no - 2, and -1.5.

Your example solves 2y ^ 2 + 7y + 6 = 0.  Premium solutions are correct:

* (- 1.5) 2 ^ 2 + 7 + 6 = 0 *(-1.5)

*(-2) 2 ^ 2 + 7 + 6 = 0 *(-2)

2 * 3 ^ 2 + 7 * 3 + 6 = 45

2 * 4 ^ 2 + 7 * 4 + 6 = 66

Another approach: factor(2y^2+7y+6).  First returns (y + 2) *(2*x+3).  As you can see, defining each factor equal to zero gives the first solutions given above (-1.5 and -2).

Hope that helps!

• HP problem first Solver (bug?)

Solve (r = f ^ (a - ln (f)), f)

correctly gives the solution f = e ^(quad formula)

BUT, if I replace the 'a' in the above with any number between 0 and 1, for example, solve (r = f ^ (0, 5 - LN (f)), f), it gives an incorrect answer.

What it does is to replace the 1/2 power in the quadratic formula, by a multiple of 1/2 instead - IE. Instead of

e ^ (b + (c)^(1/2)) (correct answer).

It gives

e ^ (b + (c)*(1/2)) (it wrong - this simplifies down to something like d * r for some d - and it took me a long time to find what she does!)

is this a bug with the command solve or I just hurt?

I noticed a similar problem when solving 2nd order of. When simplifying a solution (using the display button 'to increase'), he sometimes changes things like e ^(x*3) in e ^(x^3). Unfortunately I don't have a simple example of it yet!

Three things here.

First of all, it's really not a good idea to use tiny e as a variable because that could also be interpreted as e ^ 1 and it can be confusing, that's who. Second, when you put an approximate value as 0.5 you no longer are not a symbolic resolution. Like most systems of CASE 1.  is interpreted as "an approximate 1 floating-point value" and not "and exact symbolic whole." You should do an "exact (0.5)' instead.5 or well" 1/2 "directly.". "

Thirdly, I think you may have spotted a problem. Well, this has already been resolved and runs a connectivity kit update, you will have the version the most recent where it works correctly even solve approximately.

• XML export Final Cut Pro crashes first

No matter what I try, I can't create XML export. It always hangs at 'simplification project. Ive tried import just the sequence I need in an empty project. I tried the sequence of project management down by consolidating and also copy all of the files, but the result is the same. The sequence is 1080 p and 4 k and 2 k media, but even when I project manage it and rendering 1080 p files it crashes at the same place.

I found my problem/bug. I had an audio effect applied to a path that was the cause of the crash. I missed the first time because I had deleted all the audio clips, so I don't think looking for audio effects.

I had a lot of problems ranging from the first at will via XML. Especially if a project has been consolidated. Hold that there is a more reliable way...

• Preview.app stuck on the first page of the PDF in single page mode

I regularly Preview.app view PDF files and want to use the "Single Page" function to display an entire page at one time. I have 'Single Page' display set as the default behavior.

Lately when I open a PDF file, they properly open the first page, but I am unable to navigate to another page via the drop-down page, touch up/down arrow. If the PDF file has a table of contents, I am able to go beyond the first page through it and then proceed to navigate normally. If it is not a table of contents, the only solution is to continuous scrolling mode and continue to navigate beyond the first page.

It's very annoying! Unfortunately, I can't remember where this started happening. It could be when I upgraded to MacOS Sierra, but I can't confirm.

Everyone else see this behavior?

Hold down the Option/ALT key, then use the cursor to the TOP or to the BOTTOM of the key.

• soon my first macbook pro purchase. Designer. Help

Hey there guys!

I will buy my first Macbook pro soon.

I am a student of Visual communication, which means that I work a lot with Adobe

(Photoshop, Illustrator, InDesign, After Effect, esc.)

I mean, photo-manipulation, illustration, video art... heavy files.

While Mac should I buy? What CPU? is the difference between graphics cards questions?

and how it will affect my work?

Thank you!

My philosophy has always been to buy the best that I can afford both.  This would mean, for me, a maxed out 15 "MacBook Pro (which is what I bought this last June).

But I wonder: do you really need a laptop (MacBook Pro) or something like an iMac would work for you?

You get better performance with the iMac, everything simply because you are not paid for the necessary solidity with a laptop.  You also get a larger screen, faster processor and more memory (32GB available).

• Since the last update, I can not choose the music I bought for the first download on my phone

Since my last update, I can not get music on my phone, re upload it, music that I bought in the past

Hello victoriafromrodeheath,

I understand you have updated your iPhone 6s more iOS 10.0.2, but you can not access your purchased music. The first thing I would say is to leave the music app, sign out of the iTunes (from the settings app) account and restart your iPhone.  Then try to access your purchased again music.   Here are a few resources to explain this in more detail:

Open one session with another Apple ID on your iPhone, iPad or iPod touch

### iTunes, App Store and iBooks

1. Tap Settings > iTunes and App Store.
3. Click sign out.

4. Go to settings > iTunes and App Store.

### On an iPhone or iPod touch

1. Open the iTunes Store app.
2. At the bottom of the screen, tap more > buy > music.
3. Press "not on this iPhone" or "not the iPod."
4. Find the song you want to download, and then type it.

Take care.

The circle of rainbow of spinning of death continues to run so I am not able to get any other repair mechanism.

Anyone have any ideas on how to proceed?  The iMac is obviously not able to boot to the hard drive.

This probably means the HD has failed and must be replaced. How you proceed, is to take the computer to your local Apple authorized provider who can help replace the disk and get you back in business.

• Question about pre-ordered Album, (first time)

For my birthday my sister gave me a \$ 25 Itunes gift card and I went and pre-ordered the new Album of Metallica Deluxe, (The Set 3 disc) and I confirmed my purchases of 14.99 and my question is,.

Has paid for the entire album in full, or each track when you click on the pre-ordered button? I am responsible for the 1.29 for the first single and again here second single, (two songs)

Will need me even more money or the 14.99 will always cover the entire album?

Will need me even more money or the 14.99 will always cover the entire album?

14.99 + tax will cover it.

When you pre-order, you pay for the titles as they become available and then pay the balance when the full album is available.  In the end, you have the complete album for the price of the correct album.
