Tan Function [Runtime]/text/sbasic/shared/03080104.xhpSun Microsystems, Inc.converted from old format - fpeTan functionTan Function [Runtime]Determines the tangent of an angle. The angle is specified in radians.i71396Using the angle Alpha, the Tan Function calculates the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right-angled triangle.Tan(Alpha) = side opposite the angle/side adjacent to angleSyntax:Tan (Number)Return value:DoubleParameters:Number: Any numeric expression that you want to calculate the tangent for (in radians).To convert degrees to radians, multiply by Pi/180. To convert radians to degrees, multiply by 180/Pi.degrees=(radiant*180)/Piradiant=(degrees*Pi)/180Pi is approximately 3.141593.
