Final Answer
Step-by-step Solution
Specify the solving method
Simplifying
Apply the integral of the cosine function: $\int\cos(x)dx=\sin(x)$
Evaluate the definite integral
The sine of $\frac{\pi}{2}$ equals $1$
The sine of $0$ equals $0$
$x+0=x$, where $x$ is any expression
Simplify the expression inside the integral
