3 ________ -3*\/ cos(x)
-3*cos(x)^(1/3)
The derivative of a constant times a function is the constant times the derivative of the function.
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of cosine is negative sine:
The result of the chain rule is:
So, the result is:
The answer is:
sin(x) --------- 2/3 cos (x)
2
3 ________ 2*sin (x)
\/ cos(x) + -----------
5/3
3*cos (x)
