Tan (Tan)

This function is available on the Add Study window and in the Formula Toolbox.

The Tan function takes the selected chart value, converts it into radians, and calculates a tangent value. For example, the tangent value of 1090 would be .13. This value is calculated as follows:

1090/(2*pi) = 173.478                      Calculates the laps around the unit circle

.478 * (2*pi) = 3.00894                    Takes the leftover lap and converts it to radians

Sin( 3.00894) radians = .13226249     Calculates the sine for the calculated radians

Cos(3.00894) radians = .99124775      Calculates the cosine for the calculated radians

.13226249/.99124775 = .1334           Divides the sine by the cosine
