$$\int\limits_{0}^{1} 3 e^{2 x}\, dx$$

Integral(3*E^(2*x), (x, 0, 1))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int 3 e^{2 x}\, dx = 3 \int e^{2 x}\, dx$
1. Let $u = 2 x$ .
  
  Then let $du = 2 dx$ and substitute $\frac{du}{2}$ :
  
  $\int \frac{e^{u}}{2}\, du$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\text{False}$
    1. The integral of the exponential function is itself.
      
      $\int e^{u}\, du = e^{u}$
    So, the result is: $\frac{e^{u}}{2}$
  Now substitute $u$ back in:
  
  $\frac{e^{2 x}}{2}$
So, the result is: $\frac{3 e^{2 x}}{2}$
Add the constant of integration:

$\frac{3 e^{2 x}}{2}+ \mathrm{constant}$

The answer is:

$\frac{3 e^{2 x}}{2}+ \mathrm{constant}$
