Hi aspirant ,

Trigonometric functions  can be expanded in power series , which facilitates approximations of the functions in extreme cases. The angle x must be in radians.

Hope this help you

best of luck

Hey!

In Mathematics, trigonometry has a series of sinx and cosx called Fourier series which has An and Bn described as integral of sin(nx) and cos(nx) with function f(x) integrated from 0 to 2pi. Basically, it is covered in higher studies, in 2-3rd semester.

Thank you
