\int \csch(x) dx = \ln(\tanh(\frac{x}{2})) \int \sec(x) dx = \ln(\tan(x)+\sec(x))

Our calculator allows you to check your solutions to calculus exercises. It helps you practice by showing you the full working (step by step integration). All common integration techniques and even special functions are supported.

Free Integral Calculator helps you solve definite and indefinite integration problems. Also double, triple and improper integrals. Answers, graphs, alternate forms.

Free definite integral calculator - solve definite integrals with all the steps. Type in any integral to get the solution, free steps and graph.

The definite integral, denoted by $$$ \int_a^b f(x)dx $$$, represents the accumulated quantity or the net area between the curve of the function $$$ f(x) $$$ and the x-axis over the interval $$$ [a, b] $$$. According to the Fundamental Theorem of Calculus, there is a connection between the definite integral and the antiderivative:
