6-112.

Evaluate each of the following integrals without a calculator. Homework Help ✎

1. $\int−3\cos(x) \sec(x) dx$

Before integrating, simplify the integrand.

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

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

Before integrating, use exponents to rewrite the integrand.

$=\frac{16}{3}$

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