1. The problem statement, all variables and given/known data 2. Relevant equations n/a 3. The attempt at a solution I set up the intgral at integral from 0 to 5 of integral from 0 to 5y of 8e^(y^2)dxdy I solved it as an iterated integral so I solved the first part, then ended up with integral from 0 to 5 of 40ye^(y^2) Am I going about it right? Isn't there no antideriative for e^(y^2)? I dont know where to go from here in solving this Thanks everyone.
