I have a feeling it might have to do with Theorem let f(x) be a continuous function on the interval [a,b]. As you can see, it is just as simple to solve.

∫ 1 dx = x + c.

Z ax dx= ax ln(a) + c with base e, this becomes:

The power rule for integration, as we have seen, is the inverse of the power rule used in differentiation. In general, if ∫f(x) dx = ϕ(x) + c, then.
How to integrate $$\int_{0}^{\pi/2} e^{−2x}\sin(3x)\rm dx $$ i have attempted to this question with integration by parts, but i'm hitting a lot of walls.
