The formula for Fourier series is: f(x) = a_0/2 + ∑(a_ncos(nx2π/L) + b_nsin(nx2π/L)), where L is the period of the function, 'a_0' is the constant term, 'a_n' and 'b_n' are the Fourier coefficients.
Free Series Calculator helps you compute power series expansions of functions. Covers Taylor, Maclaurin, Laurent, Puiseux and other series expansions. Answers & graphs.
We can use the first few terms of a Taylor Series to get an approximate value for a function. Here we show better and better approximations for cos(x). The red line is cos(x), the blue is the approximation (try plotting it yourself) :
Free math problem solver answers your trigonometry homework questions with step-by-step explanations.
6 sie 2022 · Trigonometry/Power Series for Cosine and Sine. Applying Maclaurin's theorem to the cosine and sine functions for angle x (in radians), we get. {\displaystyle \displaystyle \cos (x)=1- {x^ {2} \over 2!}+ {x^ {4} \over 4!}-\cdots =\sum _ {n=0}^ {\infty } {\frac { (-1)^ {n}x^ {2n}} { (2n)!}}}
