Tan
Returns the tangent of the angle (expressed in radians).
Syntax
Tan(angle)
angle = angle in radians whose tangent you want to calculate
Remarks
If your angle is expressed in degrees, you can multiply it by pi/180 or use the Radians function.
The function will not return an error or infinity for Tan(PI/2), but rather a very large value, due to the numerical approximations of the value of PI/2.
Example
Tan(0) = 0Tan(PI/4) = 1
