Trigonometric Integrals


Trigonometric Integrals:Let us study about study about trigonometric integrals.Integral calculus is a branch of calculus that deals with integration. If f is a function of real variable x, then the definite integral is given by [int_a^bf(x)dx].Where a and b are intervals of a real line.Their are many steps to learn about trigonometry problems .Integral calculus can also be called as antiderivative.In this article, we are going to see identities of trigonometric integrals with example problems, which help you to study about trigonometric integrals.Study about Identities of Trigonometric Integrals:[int] sin x dx = - cos x + C

[int] cos x dx = sin x + C

[int] sec2 x dx = tan x + C

[int] cosec2 x dx = - cot x + C

[int] sec x tan x dx = sec x + C

[int] cosec x cot x dx = - cosec x + C

[int] tan x dx = ln |sec x| + C

[int] cot x dx = - ln |cosec x| + C

[int] sec x dx = ln |sec x + tan x| + C

[int] cosec x dx = ln |cosec x - cot x| + C

These identities are helpful to study about integration of trigonometric functions.Hope you like the above example of Trigonometric Integrals.Please leave your comments, if you have any doubts.
