Integral of cosx formula


$\int{\cos{x}}dx \,=\, \sin{x}+c$


$x$ is a variable and also angle of right triangle actually, and $dx$ is the element of integration. $\cos{x}$ is a trigonometric function. The integral of $\cos{x}$ function with respect to $x$ is expressed in calculus in the following way.


The indefinite integral of $\cos{x}$ function with $dx$ is equal to sum of $\sin{x}$ and constant of integration.
