How to Use
1. Enter your function using standard mathematical notation (e.g., 3x^2 + 2x)
2. Select integration variable from dropdown
3. Click Calculate to see result
4. Use Clear button to reset inputs
Supported operations: +, -, *, /, ^, sin, cos, exp. Include multiplication operators explicitly (e.g., 3*x instead of 3x).
Derivation Process
Integration calculators use algorithms based on fundamental calculus theorems. The implementation combines:
1. Symbolic computation for pattern matching
2. Numerical methods for approximation
3. Rule-based systems applying integration techniques
4. Step-by-step solution tracking
Our calculator uses Riemann sum principles and antiderivative rules, combining power rule, trigonometric identities, and exponential integration formulas for basic function integration.
FAQs about Integration Calculator
1. What types of integrals can this calculator solve?
This calculator handles basic indefinite integrals of polynomial, trigonometric, and exponential functions. It uses standard integration rules for common functions but may not support very complex integrals requiring special techniques.
2. How accurate are the results?
Results are mathematically exact for supported functions using symbolic computation. For unsupported functions, it uses numerical approximation methods with precision up to 6 decimal places.
3. Can I use this for definite integrals?
While primarily designed for indefinite integrals, you can calculate definite integrals by first finding the antiderivative then manually applying the Fundamental Theorem of Calculus to evaluate at limits.
