Integration Techniques Supported

Our advanced online integral calculator supports all major integration techniques used in calculus:

Substitution Method
Also known as u-substitution, this technique is used when an integral contains a function and its derivative. The calculator identifies suitable substitutions to simplify the integral.
Integration by Parts
Based on the product rule for differentiation, this method is used for integrals of products of functions. The calculator applies the formula ∫u dv = uv - ∫v du.
Partial Fractions
Used for rational functions, this technique decomposes a complex fraction into simpler fractions that can be integrated individually.
Trigonometric Substitution
For integrals containing expressions like √(a²-x²), √(a²+x²), or √(x²-a²), the calculator uses trigonometric identities to simplify the integral.
Numerical Integration
For definite integrals that cannot be solved symbolically, the calculator uses numerical methods like Simpson's Rule or Gaussian Quadrature to approximate the value.
Improper Integrals
The calculator can handle integrals with infinite limits of integration or discontinuities within the integration interval by taking appropriate limits.
