To find the double integral, we find the definite integral step by step for each boundary value of ‘x’ and ‘y’.

Double integral calculator is the instant online tool which can find the double integral of a given function.

First find the definite integral of ‘2xy’ treating ‘x’ as a constant, we get

∫

(x*1

When x=3 > (3

When x=1 > (1

9/2 – 1/2 = 4

First find the definite integral of ‘2y+3x’ treating ‘x’ as a constant, we get

∫

(2

When x=4 >3(4)+ 3(16/2)=36

When x=2 > 3(2)+ 3(4/2) = 12

36-12 = 24
