# Simple 2 variable integral just want to check my answer

• Daveyboy
In summary, a simple 2 variable integral is an integral with two variables, typically represented by x and y. To solve it, you can use basic rules of integration and identify limits of integration. Checking the answer ensures correctness and can be done with a calculator or differentiation. Common mistakes to avoid include incorrect limits, forgetting the chain rule, and algebraic errors.

f(x,y)=x+y
region is the triangle with vertices at (0,0) (2,0) (0,1)

I got 1/3

don't have maple handy, could anyone check if this is right?

I get 1.
I'm pretty sure of this answer, because I did this problem in two different ways, and got the same answer both ways.

thanks i see it now
