Question
Jause the series ER=1(41)kt1) =
(-1)k+1xk
determine the Maclaurin series and the interval of convergence for the function
f(x) = ln (1-5x²). Write out the series using summation notation and write it out as a sum of at
least the first 4 terms (with ellipsis).
b)
Use the series for f(x) = ln (1-5 x²) that you found in part (a) to evaluate the limit:
limx-0
= In (1+x), for-1 < x≤ 1 to
5x²+In(1-5x2)
3x4
