Odd & Even Functions (was thread "Fourier Series") 1. The problem statement, all variables and given/known data determine if the functions below are odd even or neither: a) f(x)=x^2+2 b) f(x)=(x^2+2)tan(x^2) c) f(x) = (x^2+2)sin(x)tan(x^2) 2. Relevant equations even - f(x) = f(-x) odd - f(-x)=-f(x) 3. The attempt at a solution I've managed the first algebraically: x=1 f(1)=1+2=3 x=-1 f(-1)=1+2=3 so f is even I reckon I need to do the same for the next function however do not know how to use tan in that equation. Any help is appreciated.
