Evaluate an Integral

Step 1:

Enter an expression below to find the indefinite integral, or add bounds to solve for the definite integral. Make sure to specify the variable you wish to integrate with.

Step 2:

Click the blue arrow to compute the integral.

More Information

To get started, try working from the example problem already populated in the box above. Just click the blue arrow and you'll see a solved example. Modify that expression as needed. A few examples of solved integrals are provided below as well. These are the types of problems you can solve with this tool.

Remember, these solvers are great for checking your work, experimenting with different equations, or reminding yourself how to work a particular problem. Maybe you just need a quick answer at work and don't want to solve the problem by hand. But if you're working on homework your teacher is going to want to see how you solved the problem step-by-step to make sure you understand the process. It's not just about getting the right answer (afterall, a computer can do that!) but learning how integrals behave and how they can be used. So, consider going back to our list of calculus lessons to review.

Examples solved with the tool above:

Solve: \( \int_0^5 4xdx \) Solution: \(50\)

Find the indefinite integral: \(\int 4x^2+7\) Solution: \( \frac{4}{3}x^3+7x+C\)

Integrate the sine: \(\int_0^\pi sinx\) Solution: \(2\)

Further Reading

You might be looking for other lessons that cover integrals and integration to help further understand what the tool above is actually doing. After all, it does you no good to simply have the answer unless you know it's right and why it's right!
