The word tangent is a word which is associated with a right-angled triangle. It is defined as the ratio of the length of the side which is opposite to the right angle to the length of the side which is adjacent to the right angle. The tangent of an angle in a triangle which has a right angle (that is a triangle with one of its angles at an angle of ninety degrees) is abbreviated as tan x. In tan x, the letter x is substituted for the angle.

It is a concept in trigonometry. Tan x is equivalent to the ratio of sin x to because x. Sin x is the length of the side which is opposite to the right angle and because x is the length of the side which is adjacent to the right angle. The word tangent is defined as a line which touches a given curve at a single point.
