Improper Integral Calculator - Evaluate Divergent - Interactive Online Tool

Improper Integral Calculator

Evaluate convergent and divergent integrals with infinite limits

f(x)

Use ∞ for infinity, -∞ for negative infinity. Enter 0 for discontinuities at the origin.

Common Improper Integrals:

Improper Integral Types:

  • Type I: Infinite limits of integration (∫[a,∞] or ∫[-∞,b] or ∫[-∞,∞])
  • Type II: Discontinuous integrand at one or both bounds
  • p-Test: ∫[1,∞] 1/x^p dx converges if p > 1, diverges if p ≤ 1
  • Comparison Test: Compare with known convergent/divergent integrals

💡 Improper Integral Tips:

  • • Always convert improper integrals to limits of proper integrals
  • • Use the p-test for integrals of the form ∫1/x^p: converges if p > 1
  • • Exponential functions like e^(-x) typically lead to convergent integrals
  • • Logarithmic singularities (like ln(x) at x=0) often converge
  • • When in doubt, use comparison tests with known convergent/divergent integrals
  • • Be careful with discontinuities - they require separate limit analysis
