7-59.

Differentiate.

1. $y^2 = 3\operatorname{cos} x$

Use implicit differentiation. Alternatively, you could simplify to '$y =$' form.

1. $y =\operatorname{tan}^2( \sqrt { x } )$

Use the Chain Rule to differentiate. You may have to use it more than once.

1. $y =\operatorname{sin}(\operatorname{cos} x)$

Use the Chain Rule to differentiate.
