Trigonometric functions

Note All trigonometric functions use radians as the unit of measure. Once you have a result, you can convert the radians into degrees using the Degrees function.


This function	Does this
Acos	Returns the arccosine (Acos), or inverse cosine, of a number.
Asin	Returns the arcsine (Asin), or inverse sine, of a number.
Atan	Returns the trigonometric arc tangent (Atan), or inverse tangent, of a number.
Cos	Returns the cosine (Cos) of angleInRadians.
Degrees	Converts angleInRadians to degrees.
Pi	Calculates the value of the constant Pi.
Radians	Converts angleInDegrees to radians.
Sin	Returns the sine (Sin) of angleInRadians expressed in radians.
Tan	Returns the tangent (Tan) of angleInRadians.
