Integral of eˣ

∫ex dx=ex+C\int e^{x}\,dx = e^{x} + C

eˣ is its own derivative, so it is also its own antiderivative (plus a constant).

Step by step

  1. Exponential rule

    ∫eᵘ du = eᵘ.

    ∫ex dx=ex\int e^{x}\,dx = e^{x}
-2-1.5-1-0.50.511.522468
  • f(x) = eˣ
  • F(x) + C

Every choice of C gives a valid antiderivative, since shifting up or down doesn’t change the slope.

Questions students ask

What is the integral of eˣ?

∫ex dx=ex+C\int e^{x}\,dx = e^{x} + C.

How do you integrate eˣ?

eˣ is its own derivative, so it is also its own antiderivative (plus a constant).

How can I check the answer?

Differentiate it: the derivative of exe^{x} is exe^{x}. CalcViz checks every antiderivative this way before showing it.
