The following is a list of
integral
In mathematics, an integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data. The process of finding integrals is called integration. Along with ...

trigonometric functions
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in a ...
. For antiderivatives involving both exponential and trigonometric functions, see
List of integrals of exponential functions. For a complete list of antiderivative functions, see
Lists of integrals. For the special antiderivatives involving trigonometric functions, see
Trigonometric integral.
Generally, if the function
is any trigonometric function, and
is its derivative,
:
In all formulas the constant ''a'' is assumed to be nonzero, and ''C'' denotes the
constant of integration
In calculus, the constant of integration, often denoted by C (or c), is a constant term added to an antiderivative of a function f(x) to indicate that the indefinite integral of f(x) (i.e., the set of all antiderivatives of f(x)), on a connecte ...

Integrands involving only
sine
In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opp ...
