5-106.

Use your derivative tools to find the second derivative,

, of each function below. Homework Help ✎ *y*= csc^{2}*x*− cot^{2}*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.
