How to evaluate where is the box determined by
, , and ?
Hello,
The integral can be written this way :
$\displaystyle \left(\int_0^5 dz\right) \left(\int_0^2 \int_0^1 ye^{-xy} ~ dx dy\right)$
because there is no "z" in the integrand.
Now for the second integral, it can be written this way (maybe you'll see more precisely how to proceed) :
$\displaystyle \int_0^2 \left(\int_0^1 ye^{-xy} ~ dx\right) ~ dy$
In order to calculate the integral in the parentheses, if you don't know what to do, make a substitution $\displaystyle t=-xy$
If you still don't get the answer, then it would be nice you show your work
