Example Question #221 : Finding Integrals

$\begin{align*}&\text{Evaluate the integral: }\\&\int_{-12}^{-8.5}(\frac{(21sin(x + 1))}{4})dx\end{align*}$

Possible Answers:

-0.21

-0.26

-0.82

-1.80

Correct answer:

-1.80

Explanation:

$\begin{align*}&\text{In performing an integral, familiarity with derivative rules}\\&\text{can prove useful. After all, an integral is essentially the}\\&\text{opposite operation of a derivative. Consider how in a derivative}\\&\text{we’d use the chain rule to multiply the derivative of the “inside”}\\&\text{of a function by the derivative of the outside? Integrals, in}\\&\text{similar fashion, entail a division.}\\&\text{Utilizing integral rules:}\\&\int[sin(ax)]=-\frac{cos(ax)}{a}\\&\int_{-12}^{-8.5}(\frac{(21sin(x + 1))}{4})dx=-\frac{(21cos(x + 1))}{4}|_{-12}^{-8.5}\\&\text{Now we just subtract the function value at the lower bound from that of the upper bound:}\\&\int_{-12}^{-8.5}(\frac{(21sin(x + 1))}{4})dx=-\frac{(21cos((-8.5) + 1))}{4}-(-\frac{(21cos((-12) + 1))}{4})\\&\int_{-12}^{-8.5}(\frac{(21sin(x + 1))}{4})dx=-1.80\end{align*}$
