Problem 37

Although it is often true that a double integral can be evaluated by using either $d x$ or $d y$ first, sometimes one choice over the other makes the work easier. Evaluate the double integrals in Exercises 37 and 38 in the easiest way possible.
$$\iint_{R} x e^{x y} d x d y ; \quad 0 \leq x \leq 2,0 \leq y \leq 1$$
Problem 38

Although it is often true that a double integral can be evaluated by using either $d x$ or $d y$ first, sometimes one choice over the other makes the work easier. Evaluate the double integrals in Exercises 37 and 38 in the easiest way possible.
$\iint_{R} 2 x^{3} e^{x^{2} y} d x d y ; \quad 0 \leq x \leq 1,0 \leq y \leq 1$
Problem 39

Evaluate each double integral.
$$\int_{2}^{4} \int_{2}^{x^{2}}\left(x^{2}+y^{2}\right) d y d x$$
Problem 40

Evaluate each double integral.
$$\int_{0}^{4} \int_{0}^{4^{x}} \frac{\sqrt{x y}}{2} d x d y$$
Problem 41

Evaluate each double integral.
$$\int_{0}^{4} \int_{0}^{x} \sqrt{x y} d y d x$$

Okay, Another volume problem. So instead of our double integral x and Y are both going from zero to one in a grand A Z to the explosive all high So this is a supersymmetric and a girl I'Ll just put the eggs first of the matter Get on the wife first, Ok? And so anti derivative here. Well, it's just it's stuff. I mean, this is just about as easy as it gets. Justine, evaluate zero to one value extra zero one. So that's just okay. Me too. The one plus why minus c to the y. Okay. And then this is pretty straight forward again. Anti derivatives or just the exponential is themselves. You won. Okay, so if we evaluate at one will get he squared minus a and then minus evaluated zero. Me too. The one minus one. So what is that? He squared minus two e Plus, what
