Find the Maclaurin series for f(x) using the definition of a Maclaurin series. [Assume that f has a power series expansion. Do not show that
Rn(x) → 0.]
f(x) = ln(1 + 5x)
Find the associated radius of convergence R.
ln(1+5x) = (5x)-(5x)^2/2+(5x)^3/3-(5x)^4/4+.... (-1)^(n-1)*(5x)^n/n+..
Radius of convergence is |5x| < 1 or |x| < 0.2
