6-26.

Examine the following derivatives. Consider the multiple tools available for finding derivatives and use the best strategy. After finding each derivative, write a short description of your method.

1. $\frac { d } { d x } [ \operatorname { sin } x \cdot e ^ { x } ]$

1. $\frac { d } { d z } [ \frac { 6 z + 1 } { 3 z - 2 } ]$

1. $\frac { d } { d t } [ \operatorname { tan } t \cdot \operatorname { cos } t ]$

$\text{tan}(t)=\frac{\text{sin}(t)}{\text{cos}(t)}$
