Homework Statement
the derivative of CSC u is CSC u times cot u times the derivative of the u
but how can I derive CSC^2 u?
2. The attempt at a solution
CSC^2 u is (CSC u)^2
The derivative is
2(CSC u)(CSC u times Cot u)(1)
another way
CSC^2 u = CSC u times CSC u
CSC u times ( CSC u Cot u )(1) + CSC u ( CSC u Cot u)(1)
Is it correct?
