I am learning Fourier series and have come across the sine, cosine, and imaginary exponential expressions. To my knowledge, these individual terms form a basis since they are all orthogonal to each other. I am just wondering: can a Fourier sine series be used to model a purely even function, such as cosx or ## x^2##? Are there any limitations with using a Fourier sine series on even functions?
