Description

All these functions work with double precision floating point numbers. They convert their argument to an IEEE 64-bit float and return a result of that type.

:  acos	arc cosine
:  asin	arc sine
:  atan	arc tangent
:  cos	cosine
:  sin	sine
:  tan	tangent
:  cot	cotangent
:  degrees	  convert an angle in radians to degrees.
:  radians	convert an angle in radians to degrees.
:  atan2	arc tangent with x and y coordinates, can return an angle in any quadrant.
:  pi	return pi.
