obtain the maclaurin series expansions of the following:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]ln(1+e^x)[/tex]

ok im quite lost..i assume you set it equal to f(x) then differentiate..but what happens when you differentiate that?

also question (b) is

[tex]\frac{x}{(e^x-1)}[/tex]

does that work down to

(e^x - 1)^-x ?

and if so..would you then differentiate the whole of the bracket? but then the chain rule comes into use doesnt it? so it would be -x times e^x?
