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

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

Detail solution

There are multiple ways to do this integral.
Method #1
1. Let $u = 2 x + 1$ .
  
  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:
  
  $\frac{e^{2 x + 1}}{2}$
Method #2
1. Rewrite the integrand:
  
  $e^{2 x + 1} = e e^{2 x}$
2. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int e e^{2 x}\, dx = e \int e^{2 x}\, dx$
  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:
      
      $\text{False}$
      
      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: $\frac{e e^{2 x}}{2}$
Method #3
1. Rewrite the integrand:
  
  $e^{2 x + 1} = e e^{2 x}$
2. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int e e^{2 x}\, dx = e \int e^{2 x}\, dx$
  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:
      
      $\text{False}$
      
      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: $\frac{e e^{2 x}}{2}$
Now simplify:

$\frac{e^{2 x + 1}}{2}$
Add the constant of integration:

$\frac{e^{2 x + 1}}{2}+ \mathrm{constant}$

The answer is:

$\frac{e^{2 x + 1}}{2}+ \mathrm{constant}$
