How to solve an integral

Now plug everything into the formula to find the integral: Finally, simplify to give: ∫ xex dx = xex − ∫ex dx = xex − ex + C. ∫ x e x d x = x e x − ∫ e x d x = x e x − e x + C. Here are the steps we followed: Choose u u and v′ v ′ (one to differentiate and the other to integrate) Differentiate u u to give u′ u ′.

Integration is the reverse of differentiation. However: If y = 2x + 3, dy/dx = 2. If y = 2x + 5, dy/dx = 2. If y = 2x, dy/dx = 2. So the integral of 2 can be 2x + 3, 2x + 5, 2x, etc. For this reason, when we integrate, we have to add a constant. So the integral of 2 is 2x + c, where c is a constant. A "S" shaped symbol is used to mean the ...More than just an online integral solver.
