What is the derivative of:v(x)=cos(-x^s+x+3)?

OpenStudy (anonymous):

is that $-x^s$?

OpenStudy (anonymous):

2...im sorry x^2

OpenStudy (anonymous):

chain rule for this one $-\sin(x^2+x+3)(2x+1)$

OpenStudy (anonymous):

Is that the chain rule written out for this problem?

OpenStudy (anonymous):

that is the answer. the derivative of cosine is minus sine, so the derivative of cosine of "stuff" is - sin( stuff) times the derivative of stuff

OpenStudy (anonymous):

the problem is not clearly written

OpenStudy (anonymous):

Perfect....thanks.

OpenStudy (anonymous):

=-sin(-sx+1)
