Indefinite Integrals Practice Problems

Problem: Indefinite Integrals #1

Evaluate:

[latex]\Large{\int(2x^2+3x-1)dx}[/latex]

Step 1:

 

We can first apply the integration to each term as follows:

 

[latex]\large{\int(2x^2+3x-1)dx = \int(2x^2)dx + \int(3x)dx – \int(1)dx}[/latex]

 

Step 2:

 

Now, we can use the integral power rule to evaluate each integral individually, as shown:

 

[latex]\large{\int(2x^2)dx = \frac{2}{3}x^3}[/latex]

 

[latex]\large{\int(3x)dx = \frac{3}{2}x^2}[/latex]

 

[latex]\large{\int(1)dx = x}[/latex]

 

Step 3:

 

Now, combining everything, we have:

 

[latex]\large{\int(2x^2+3x-1)dx = \frac{2}{3}x^3 + \frac{3}{2}x^2 – x + C}[/latex]

Step 1:

We can first apply the integration to each term as follows:


[latex]\large{\int(2x^2+3x-1)dx}[/latex]


[latex]\small{ = \int(2x^2)dx + \int(3x)dx – \int(1)dx}[/latex]


Step 2:


Now, we can use the integral power rule to evaluate each integral individually, as shown:

Problem: Indefinite Integrals #2

Evaluate:

[latex]\Large{\int(3x^4-x^3+2x^{\frac{1}{3}}-x^{-2})dx}[/latex]

Step 1:


We can first apply the integration to each term as follows:


[latex]\large{\int(3x^4-x^3+2x^{\frac{1}{3}}-x^{-2})dx}[/latex]


[latex]\small{ = \int(3x^4)dx\: – \:\int(x^3)dx + \int(2x^{\frac{1}{3}})dx\: -\: \int(x^{-2})dx}[/latex]


Step 2:


Now, we can use the integral power rule to evaluate each integral individually, as shown:
