Defines

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