1. The problem statement, all variables and given/known data Evaluate the following integral: [tex]\int \int_R x^3 y^4 dx dy[/tex] 2. Relevant equations 3. The attempt at a solution I don't even know where to start. My professor just introduced us to double integrals, now there's a strike going on at my school, so classes are cancelled, and I want to get an early start. Does anyone know a good link where they do a decent job explaining double integrals? Thank you.
