The area bounded by the curve $y = |\sin x|$ and the $x$-axis between $x = 0$ and $x = 2\pi$ is:
Step-by-Step Solution
Key Concept: Use the fact that $\sin x$ is positive on $[0, \pi]$ and negative on $[\pi, 2\pi]$ to split $|\sin x|$ into two equal-area humps, and compute the area of just one of them.
