Enter your function using standard math notation: x^2, sin(x), exp(-x^2), etc. Set the lower and upper bounds, then click Calculate to see the answer.
Examples
Solving a Trigonometric Integral
Solve the integral of sin(x) from 0 to pi.
The antiderivative of sin(x) is -cos(x). Evaluating: -cos(pi) + cos(0) = 1 + 1 = 2.
Key takeaway: This classic result equals exactly 2.
Tips for Solving Integrals
Keep these in mind when solving integrals:
- Double-check your function syntax before clicking Calculate
- Start with a known integral to verify your setup
- Use the graph to visually confirm the result makes sense
Frequently Asked Questions about Integral Solver
How do I enter my integral?
