Tool to calculate Double Integral. The calculation of two consecutive integral makes it possible to compute areas for functions with two variables to integrate over a given interval.

dCode is free and its tools are a valuable help in games, maths, geocaching, puzzles and problems to solve every day! A suggestion ? a feedback ? a bug ? an idea ? Write to dCode!

Example: Calculate the integral of $ f(x,y)=x+y $ over $ x \in [0,1] $ and $ y \in [0,2] $ $$ \int_{0}^{2} \int_{0}^{1} x+y \text{ d}x\text{ d}y = \int_{0}^{2} \frac{1}{2}y^2+y \text{ d}y = 3 $$

Enter the function on dCode with the upper and lower bounds for each variable and the calculator will return the resultat automatically.

It is possible to use variables in the bounds of the integrals:
