Defines

[AlexisVieira]

Well, I have on my nspire the switcher ndless/3.2 and I use that lots of times but when I do that I delete all of my defines and when I go to my math clessons I spend some time typing this:

Code: Select all

Define c(x,y)=ncr(x,y)
Define a(x,y)=nPr(x,y)
Define cis(x)=cos(x)+i*sin(x)
Define q1=0≤x≤π/2
Define q2=π/2≤x≤π
Define q3=π≤x≤3π/2
Define q4=3π/2≤x≤2π

which is a lot of work! -.- Is there a way to make my nspire have this functions "defined" on the reboot ?

Just put all these Defines in a Libpub program and execute it when you need it.

[AlexisVieira]

something like this?

Code: Select all

Define LibPub defines()=
Prgm
Define c(x,y)=ncr(x,y)
Define a(x,y)=nPr(x,y)
Define cis(x)=cos(x)+i*sin(x)
Define q1=0≤x≤π/2
Define q2=π/2≤x≤π
Define q3=π≤x≤3π/2
Define q4=3π/2≤x≤2π
EndPrgm

Yes.
You save that program in a document in Mylib, you "refresh the librairies", and you can use it anywhere anytime.
Once executed in any new document, you can use all the functions and constants that you have defined.

It's almost an "include"...
