Question

By using Maclauring series expand log(1+e^x)
in the power of x upto x^4​

Answer 1

thought it would be to take the series for ln(1+x) and the series for ex up to x3 and sub the second series into the first.

$ln(1+x)=x−x22+x33+$

$ex=1+x+x22+x36+$

This gave me

$56+x+3x22+2x33$

Answer 2
