For this example, i'll be considering your left integral.

34+ Sketch The Region Of Integration
Pics. In the first integral, which is like yours, you view the inner integral as happening first. First, we note what each integral is integrating with respect to.

Without understanding the regions, we will not be able to decide the limits of integrations in double integrals. Below both integral signs is r. So i want to sketch the regional integration and changed order of integration of the iterated integral where the devil integral zero to one into absurd of one of intervals.

Compute the integral from a to b

Sketch the region of integration and change the order of integration. For this example, i'll be considering your left integral. Then change the order ofintegration and evaluate.thanks. Sketch the region of integration.
