What is the second derivative of #f(x)=cot(3x^2-x)#?
Use the chain rule, which states that
Use product rule in conjunction with the chain rule again.
When doing chain rule with the cosecant function squared, the overriding issue will be the exponent, and then the cosecant.
Find each derivative.
Plug both the derivatives back in to find
This can be further simplified, if you want:
