The Fourier series simplifies if \(f(x)\) is an even function such that \(f(−x) = f(x)\), or an odd function such that \(f(−x) = −f(x)\). Use will be made of the following facts. The function \(\cos (n\pi x/L)\) is an even function and \(\sin (n\pi x/L)\) is an odd function. The product of two even functions is an even function. The coordinates of the point at the end of this arc is $(\cos x, \sin x).$ This should be your definition of sine and cosine. It is a more useful definition than anything based off of right triangles.
