Question

Find double integrationfrom 1 to 2 and then 3 to 4 (xy + e^y) dx dy​

Answer 1

Answer:

In a double integral, the outer limits must be constant, but the inner limits can depend on the outer variable. This means, we must put y as the inner integration variables, as was done in the second way of computing Example 1. The only difference from Example 1 is that the upper limit of y is x/2.
