How do you find the Maclaurin series of f(x)=cos(x^2)f(x)=cos(x2) ? Calculus Power Series Constructing a Maclaurin Series 1 Answer Wataru Sep 12, 2014 We have the Maclaurin series cosx=sum_{n=0}^infty(-1)^n{x^{2n}}/{(2n)!}cosx=∞∑n=0(−1)nx2n(2n)! by replacing xx by x^2x2, cos(x^2)=sum_{n=0}^infty(-1)^n{x^{4n}}/{(2n)!}cos(x2)=∞∑n=0(−1)nx4n(2n)!
