Describe trignometric functions ?

Answer»

Python includes following functions that perform trignometric calculations.

Function	Description
acos(x)	Return the arc cosine of x, in radians
asin(x	Return the arc sine of x, in radians.
atan(x)	Return the arc tangent of x, in radians.
atan2(y, x)	Return atan(y/x), in radians.
cos(x)	Return the cosine of x radians.
hypot(x, y)	Return the Euclidean norm, sqrt(x*x + y^y).
sin(x)
tan(x)
degrees(x)	Converts angle x from radians to degrees.
radians(x)	Converts angle x from de-grees to radians.
