Remember cos(n*pi) = (-1)^n

[@curiouscoding1230]

@@jonasasare5775 cos (-n*pi) = ??

[@jonasasare5775]

@@curiouscoding1230 no cos(pi) = -1 but here we have a variable n which will make the sign to change in the case where n is even or case where n is odd. So we have to rise it to the power of n to take care of those cases
