5-106.
  1. Use your derivative tools to find the second derivative, , of each function below. Homework Help ✎

    1. y = csc2 x − cot2 x

You could use the quotient rule AND the chain rule...Or you could rewrite y as with exponents and quickly use the Power Rule!

Rewrite y as a piecewise function. The derivative will be a piecewise function as well. So will the second derivative.
