A numeric expression containing the number of radians in the angle whose tangent is to be returned |
Returns
The tangent of number. Usage
Number is specified in radians and can be either positive or negative. The return value is single precision if the angle is an integer, currency, or single-precision value; double precision for a long, variant, or double-precision value. To convert degrees to radians, multiply by PI/180. The value of PI is 3.14159. Example
This example finds the height of the exterior wall of a building, given its roof pitch and the length of the building. Sub Button_Click Dim bldglen, wallht Dim pitch Dim msgtext Const PI = 3.14159 Const conversion = PI/180 On Error Resume Next pitch = 35 pitch = pitch * conversion bldglen = 150 wallht = Tan(pitch) * (bldglen/2) End Sub
