1. The problem statement, all variables and given/known data Let f(x) = 1/(x^2+x+1). Let f(x) = sum(from o to infinity) Cn x^n be the McLaurin Series representation for f(x). Find the value of C36-C37+C38. 2. Relevant equations 3. The attempt at a solution I got the Taylor Series: sum(from o to infinity) x^3n - sum(from o to infinity)x^(3n+1). but have absolutely no idea what to do next. Please help!!!
