So the area for y is between y equals x squared and 0, and between 0 and 1 for x.
00:18
And this is the area.
00:21
And the density is y cubed.
00:27
And first, the integral from 0 to 1 for x, and the integral from 0 to e to x power, power.
00:37
For y and then the density.
00:43
First, we solve the interior integration.
01:02
And now we want to find the anti -derivative, which is 1 over 16 times e to the power of flax.
01:12
It's from 0 to 1, and the final answer is 1 over 16 times e to the 4th minus 1.
01:22
And next, capital m of y, the integral is similar, but now it's density times x...
