anonymous · Answer

i get the bounds just the order of integration is tricking me, for

anonymous · Answer

$$\int\limits_{a}^{2}e ^{x ^{2}}dx$$

mathmate · Answer

Use a type 1 region, so it looks like
$\int_0^2\int_0^x...dy dx$
and you should do well.

anonymous · Answer

well yea i get the double integral, but for the first question i dont think i completly understand when it means, to set up an expression depending on a, then id think it should be dy

anonymous · Answer

because y=a and you would have the integral depending on y as the inner one

mathmate · Answer

You're ok with the double integral.
The function has three variables, x, y and z, thus f(x,y,z).
By setting y=a (a constant), then the function becomes f(x,a,z) which is a function of two variables, or essentially, you have to evaluate that area of W (the cross section.
