You could simplify now, if you choose.Find

Notice that

, which you found in part (a), has both and variables. So, before you evaluate, use the original equation to find the -value that corresponds with. It is possible that there will be more than one.

Use a calculator to find the THREE-values that correspond with.Evaluate

at those THREE coordinate points. Find all points where the derivative is undefined.

The derivative,

, will be undefined where the denominator equals .
