How can we find the Maclaurin series for the function f(x) = cos(x^2) and use it to approximate f(80)?

Finding the Maclaurin Series for f(x) = cos(x2) The Maclaurin series is a special case of the Taylor series centered at 0. To find the Maclaurin series for the function f(x) = cos(x2), we first recall the Taylor series expansion for cosine: cos(x) = ∑n=0∞ rac{(-1)nx2n}{(2n)!} Now, by substituting x2 for x, we get: cos(x2) … Read more
