The functions sin x and cos x can be expressed by series that converge for all values of x: These series can be used to obtain approximate expressions for sin x and cos x for small values of x : The trigonometric system 1, cos x , sin x , cos 2 x , sin 2 x , . . ., cos nx , sin nx , . . . constitutes an orthogonal system of functions on the interval [– π, π].
