Integral Calculator: Solve Definite and Indefinite Integrals (Antiderivatives)

Online integral calculator with step-by-step solutions, interactive graphs, and image scanning. Choose solution steps manually. Methods include u-substitution, integration by parts, partial fractions, trigonometric/hyperbolic/logarithmic formulas, polynomial long division, Euler substitution, binomial differentials, Weierstrass substitution, and Ostrogradsky's method. Solve definite and improper integrals using the Fundamental Theorem of Calculus.
