Question

1. Show that the given set of functions is orthogonal on the given interval {sin,cos,sin2,cos2,sin3,cos3,...};[−,]
2. What is the corresponding orthonormalset of the above orthogonalset?Note: Tri identities formula:coscos=12[cos(−)+cos(+)]sinsin=12[cos(−)−cos(+)]sincos=12[sin(−)+sin(+)]cos2θ=12[1+cos(2)]sin2θ=12[1−cos(2)]
