6-119.

Simplify the following integrals without a calculator.

1. $\int - 3 \operatorname { cos } x \operatorname { sec } x d x$

Before integrating, simplify the integrand.

$\text{Recall that }\sec(x)=\frac{1}{\cos(x)}.$

1. $\int _ { 1 } ^ { 5 } \sqrt { 5 - x } d x$

Before integrating, use exponents to rewrite the integrand.

Be sure to show the steps (including the antiderivative).
