The tangent function is the ratio of the opposite side to the adjacent side in a right triangle. Placed in a Cartesian coordinate system $$ tan\theta =y/x $$
Tan takes a corner and returns the ratio of the two right-angled sides of the right-angled triangle. This ratio is the ratio of the length of the opposite side of the corner to the length of the adjacent side in a right triangle.
When used, the calculation form is as follows:
$$ y=tangent(x) $$
