Hi,

I need help with integration. We use constants for indefinite integrals, rite?
exp(-t) and exp(2t) what are the integrals of these two? former carries a constant c but the latter does not. why so?

There are no indefinite integrals that do not have an additvie constant because the derivative of any additive constant is uniquely zero almost surely.

Int((e^2t)*dt) = ((1/2) * (e ^2t)) + C

Int((e^-t(*dt)) = -(e^-t) + C

You can check both results by differentiation
