Short Answer

Expert verified

Ans: The exact value of $\int_{- π}^{π} (1 + \sin x) d x = 2 π$

Step by step solution

Step 1. Given information.

given,

$\int_{- π}^{π} (1 + \sin x) d x$

Step 2. The objective is to determine the exact value of the definite integral.

The exact value is calculated as shown below,

$\begin{aligned} \int_{- π}^{π} (1 + \sin x) d x \\ = \int_{- π}^{π} (1) d x + \int_{- π}^{π} (\sin x) d x \\ = [x]_{- π}^{π} + [- \cos x]_{- π}^{π} \\ = π + π - \cos π + \cos (- π) \\ = 2 π + 0 \\ = 2 π \end{aligned}$

Therefore, the exact value is, $2 π .$

Step 3. Check the answer using a graph.

The required graph is,
