Question

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

Answer 1

is that
\[-x^s\]?

Answer 2

2...im sorry x^2

Answer 3

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

Answer 4

Is that the chain rule written out for this problem?

Answer 5

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

Answer 6

the problem is not clearly written

Answer 7

Perfect....thanks.

Answer 8

=-sin(-sx+1)
