Find the taylor series for f(x) centered at the given value of a. [assume that f has a power series expansion. do not show that r(x) → 0.] . 4cos(x) at a= 3pi

Base in your question that ask to find the Taylor series for function f(x) at a given value of A. And assume that F has a power series expansion. So to solve this you must first derive its function in to a standard series for taylor. Then after that you will came up with a solution of Ts=c0(x−a)^0/0! + c1(x−a)^1/ 1! + c2(x−a)^2/2!+c3(x−a)^3/3!
