Question

What is the integration of 2x

Answer 1

So the integral of 2 can be 2x + 3, 2x + 5, 2x, etc. For this reason, when weintegrate, 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 integral of, and dx is written at the end of the terms to beintegrated, meaning "with respect to x".
