is the derivative of xsinx
OpenStudy (anonymous):
and the derivative of the top is 1-cosx, which as x approaches 0 = 0, cuz cosx approaches 1
OpenStudy (anonymous):
what about xcoxx?
OpenStudy (anonymous):
of course, then u need to do it again lol, and xcosx derived equals -xsinx +cosx
OpenStudy (anonymous):
so the answer is 0 right?

so the final thing will be sinx/(-xsinx +2cosx)
OpenStudy (anonymous):
and yes, the answer is 0
