I need to show that this is not linear. From what I understand, sinx makes this a nonlinear function because it is a periodic function and only defined if: -π/2 ≤x≤π/2. Is my conjecture correct? How can I prove it?
Thanks for your help.

A function f(x) is linear iff for all x, y in the domain
and for any scalar a and x in the domain.
