1. The problem statement, all variables and given/known data The function [tex]f(x)=5xarctan(3x)[/tex] is represented as a power series. Find the first few coefficients in the power series. 2. Relevant equations The power series is represented in the form [tex]sum(Cn*x^n)[/tex] 3. The attempt at a solution I've attempted to write the function as an integral, and split the 5x with the trignonometric component. After doing this (and writing a power series), I'm not getting the right answer. Is something wrong with my approach? Thank you in advance.
