Hello,

How can I specify n integer in my classpad 330 ? I would like to have automatically these simplifications : cos(Pi*n)=(-1)^n and sin(Pi*n)=0, particulary to calculate fourier coefficients.

Thank you !

Use constn(1) instead of n and sin(pi*constn(1)) will be simplified to 0, although cos(pi*constn(1)) doesn't work.
