Integrals

Indefinite integrals - substitution, parts, rational functions, and standard techniques.

These practice problems ask you to find an indefinite integral: an antiderivative you can check by differentiating. The set assumes you can differentiate. It stops short of areas and numerical bounds, which belong to the definite integral. Each solution is written out step by step, so the choice of method is visible, not only the final formula.

Algebraic Integrands and Rational and Quadratic start with polynomials, rational functions, and completing the square. Exponential and Logarithmic and Trigonometric Integrals collect the standard forms worth recognizing on sight. Hyperbolic Integrals and Integration by Parts is the main tool for products. Roots and Binomials, Partial Fractions, and Substitutions, including trigonometric substitutions, handle integrands that do not fall to a single rule. Advanced Techniques gathers problems that need two or more of those methods in sequence.

Differentiate your answer before you open the solution. Easy problems use one technique; Hard problems hide which substitution fits. Come here from Differential Calculus if the derivative rules are still new. When antiderivatives are reliable, go to Definite Integrals to evaluate them on an interval, and then to Applications of Definite Integrals for area, volume, and work.
