How do I calculate tan?
The tangent is a trigonometric function, defined as the ratio of the length of the side opposite to the angle to the length of the adjacent side, in a right-angled triangle. It is called “tangent” since it can be represented as a line segment tangent to a circle. In the graph above, tan(α) = a/b and tan(β) = b/a.
