How were double integrals calculated before Fubini

Webx = 0 and x = 5. First you set up your integral ∫ 5 0 xdx. Next you find the indefinite integral. ∫xdx = 1 2 ⋅ x2 + C. Now you plugin the 5 and the 0 and solve. (1 2 ⋅ 52 + C) − (1 2 ⋅ 02 +C) = 12.5. Because this example forms a triangle, we can check the answer with the equation for the area. A = 1 2 ⋅ 5 ⋅ 5 = 12.5.
