Trigonometric Tangent Function - Tan(deg)

Tangent or Tan function is defined as a value (or the ratio) obtained by dividing the Opposite Side by Adjacent Side with reference to angle (x) or (y) being measured in degrees a Right Angled Triangle.
It also is same as
tan(angle) = Sin(angle)/Cos(angle).
The value of Tangent function varies from a infinite negative value (e.g. 90.00001) to positive infinite value (e.g. 89.99999).
The value of sin(90) = 1 and cos(90) = 0, and hence
tan(90) = sin(90)/cos(90),
becomes 1/0 a indeterminate value.
The tan(degree) values are shown in Table A.


Tan(x) = Opposide Side/Hypotenuse = BC/AB	Tan(y) = Opposide Side/Hypotenuse = AB/BC
