In Exercises 49–58, sketch the region determined by the iterated integral and then evaluate the integral. For some of these integrals, it may be helpful to reverse the order of integration.

∫01∫-exexsinexdydx

Short Answer

Expert verified

Value of the given integral is:2-cose+cos1

Step by step solution

01

Step 1. Given Information

An integral,∫01∫-exexsinexdydx

02

Step 2. Sketching the region of integration

Region of integration is shaded in the graph below.

03

Step 3. Evaluating the given iterated integral  

Given integral,

∫01∫-exexsinexdydx=∫01sinexy-exexdx=∫01sinex(ex-(-ex))dx=∫012exsinexdx

Put, ex=t,exdx=dt,

We get, ∫1e2sintdt

=2-cost1e=2-cose+cos1
