6-35.

Examine the integrals below. Consider the multiple tools available for integrating and use the best strategy for each. Evaluate each integral and briefly describe your method. Homework Help ✎

1. $\int ( 6 ^ { x } - 3 \operatorname { sec } ( x ) \operatorname { tan } ( x ) ) d x$

What two functions have derivative of 6x and 3sec(x)tan(x), respectively?

$\frac{6^{x}}{\text{ln} 6}-3\text{sec}x+C$

1. $\pi \int _ { 0 } ^ { 2 } ( ( 2 x ) ^ { 2 } - ( x ^ { 2 } ) ^ { 2 } ) d x$

(2x)2 − (x2)2 = 4x2x

1. $\int _ { 1 } ^ { 4 } \frac { 3 x ^ { 2 } + 13 x - 10 } { x + 5 } d x$

Factor.

1. $\int 6 m ^ { - 4 / 3 } d m$

Undo the Power Rule.
