Given command for Hp prime? - Lord_Spooglypuff - 10-28-2020 07:19 AM
Hi all.
I have recently switched out my Ti nspire for a hp prime, and I am struggling to figure out how to set restrictions on equations on the CAS.
For example, on the 84 plus and nspire, restricting equations is done using set notation:
eg: solve(v^2=u^2+2a*s)|v=50,u=5
So how would I convert that to hp prime syntax? I have been doing some digging, and I found that the given symbol exists, but I can't figure out how to get it to work without just displaying syntax errors.
Thank you for your help.

You simply enter: solve(v^2=u^2+2*a*s,a)|v=50,u=5 using CAS, before that you should make sure the variables are empty: purge(s), purge(a). The | can be taken from the patterns found on the keyboard.

Also, note the additional characters that were added:
solve(v^2=u^2+2*a*s,a)|v=50,u=5

I was in CAS mode, but it is still giving out a syntax error.
Does anyone else still know what's happening?

After you insert the "|" from the 3rd key in the top row, don't cursor up before you enter the "v=50,u=5 ".

It works now, I realized that I was getting the pipe symbol from the character menu on the first key.
Since I used the symbol on the third key instead, it's working
Thank you very much

Well, the easiest way is to follow rprosperi's comments.
Top key row, 3rd key, top menu row, 3rd entry .. |
No need to dig through 'Chars' menu.
