let u be a function of x ...

so if the original equation was

the derivative would be

=

correct? - Feb 19th 2009, 06:10 PMskeeter
no ... you have to use the product rule

I don't know why i keep making these simple mistakes. so if we want the derivative it would be

I am getting stuck here. - Feb 19th 2009, 06:40 PMskeeter
