Question:medium

The value of $\iint_S \cos(x) \sin(y) \, dx \, dy$ is, where $S$ is $\left[0, \frac{\pi}{2}\right] \times \left[0, \frac{\pi}{2}\right]$

Show Hint

Whenever double integral limits are constants and the integrand separates into $g(x)h(y)$, always split it into two single 1D integrals immediately to save computation time!
