find coefficient of x^4 in the MAclaurin series for f(x)=e^sinx
ok... so taking derivatives 4 times for this function...gave me a mess! @.@
can someone help me in simplying the derivatives...?
then for 2. is it -sinxe^sinx-sinxcosxe^sinx...?
= . = I'm getting lost with these derivatives...
same for e^3xcos2x... gets sooo complicated...
