In a right-angled triangle, the tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
tan(x) = O = Sin(x) A Cos(x)
For example, in this triangle:
the tangent of A (tanA) is 1.33, because the ratio of th opposite side(4) to the adjacent side(3) is 4/3.
Graph of tan(x):
- Tan(x) has vertical asymptotes at values where cos(x) = 0, as the tangent is undefined for these values (cannot divide by zero).
-Tan(x) has a period of π
