(a) Are the functions h(a) 1,(z) cos (2z) and fs(z) sin(x) linearly independent? (b) How about the functions f(a)1, Ja(ar)sin (a) and fs(a)sin ()? Why or why Why or why not? not? (Hint: Plug in 3 different values of z to get a linear system for the coefficients in the definition of linear independence.)
