1. The problem statement, all variables and given/known data Use a known Maclaurin series to compute the Maclaurin series for the function: f(x) = x/(1-4(x^2)) 2. Relevant equations 1/(1-x) = ∑x^n 3. The attempt at a solution I tried removing x from the numerator for: x ∑ 1/(1-4(x^2)), which would end up through substitution as x ∑ (4^n)(x^2n). Not too sure this is correct use of substitution however.
