Integration Formulas (Table of Indefinite Integrals)

Related calculator: Integral (Antiderivative) Calculator with Steps

Below is a table of Indefinite Integrals. With this table and integration techniques, you will be able to find majority of integrals.

It is also worth noting that unlike derivative (we can find derivative of any function), we can't find integral of any function: this means that we can't find integral in terms of functions we know.

Examples of such functions are $$$\int{{e}}^{{{{x}}^{{2}}}}{d}{x}$$$, $$$\int\frac{{{\sin{{\left({x}\right)}}}}}{{x}}{d}{x}$$$, $$$\int\sqrt{{{{x}}^{{3}}+{1}}}{d}{x}$$$ etc.
