Integrates irrational functions (involving square roots, etc.) using substitution to rationalize.
For functions with √(ax+b):
Substitute u = √(ax+b), then u² = ax+b, 2u du = a dx
For functions with √(x²±a²): use trigonometric substitution
Substitution rationalizes irrational functions

About this calculator
Overview
Irrational Function Integral Calculator evaluates Irrational Function Integral for the math / integration library. Primary input cue: Irrational Function [required]: Function involving square roots or other irrational expressions. Method anchor: For functions with √(ax+b): Substitute u = √(ax+b), then u² = ax+b, 2u du = a dx For functions with √(x²±a²): use trigonometric substitution. Substitution ratio.
When to use
Use Irrational Function Integral Calculator when you already know the inputs and need irrational function integral without setting up a spreadsheet.
Inputs explained
- Irrational Function [required]: Function involving square roots or other irrational expressions
Formula / method
For functions with √(ax+b): Substitute u = √(ax+b), then u² = ax+b, 2u du = a dx For functions with √(x²±a²): use trigonometric substitution. Substitution rationalizes irrational functions (calculator id: irrational-function-integral-calculator).
Worked example
Worked values: function = x/sqrt(x+1) → integral = (2/3)(x+1)^(3/2) - 2√(x+1) + C, substitution = u = √(x+1)
Interpreting results
If irrational function integral looks implausible, re-check units and which field is optional vs required.
Assumptions
- Irrational Function Integral is computed only from the fields you enter on this calculator. [irrational-function-integral-calculator]
- The wired execution function for `irrational-function-integral-calculator` is the source of numerical behavior.
- Real-number arithmetic is used unless irrational function integral explicitly needs integers.
Limitations
- Edge cases outside the intended domain of irrational function integral may error or look unstable—treat them as out of scope.
- If multiple conventions exist for irrational function integral, this calculator uses the convention implemented in its engine path.
- Complex/branch cuts and undefined points are not always interactively annotated for irrational function integral.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
