Integral of e^2x | e^2x Integration

The integration of e2x is equal to e2x/2. In this post, we will learn how to integrate e to the 2x. The integration of e2x can be derived directly from the formula of the integral of emx which is given below:

$\int e^{mx} dx=\dfrac{e^{mx}}{m}+C$ where C is an integration constant.

Putting m=2 in the above formula, the integral of e to the 2x is equal to

$\int e^{2x} dx=\dfrac{e^{2x}}{2}+C$.

What is the Integration of e2x

Question: What is the integration of e2x?

Answer: The integration of e2x is $\dfrac{e^{2x}}{2}$.


We will find the integration of e2x by the substitution method, we will follow the below steps.

Step 1: Let us put $t=2x$.

Differentiating both sides with respect to x, we have


$\Rightarrow dx= \dfrac{dt}{2}$

Step 2: Let us now put the values of 2x and dx in the original integration. By doing so, we will get that

$\therefore \int e^{2x} dx = \int e^t \dfrac{dt}{2}$

$=\dfrac{1}{2} \int e^t dt$ as 1/2 is a constant, so we can take it out of the integration.

$=\dfrac{1}{2} e^t +C$ as the integration of ex is ex

$=\dfrac{1}{2} e^{2x}+C$ as t=2x.

So the integration of e2xdx is $\dfrac{1}{2} e^{2x}+C$ where C is an integral constant.

Definite integral of e2x

Question: Find the definite integral $\int_0^1 e^{2x} dx$.


We have shown above that the integration of $e^{2x} dx$ is $\dfrac{1}{2} e^{2x}$. Thus, we have that

$\int_0^1 e^{2x} dx$

$=[\dfrac{1}{2} e^{2x}]_0^1$


$=\dfrac{1}{2}(e^{2 \cdot 1} -e^0)$

$=\dfrac{1}{2}(e^2 -1)$

So the definite integration of e2x from 0 to 1 is equal to (e2-1)/2.
