Last Updated: 23rd January, 2020

**tan**x = sin x cos x . The cotangent of x isdefined to be the cosine of x divided by the sine of x: cot x = cosx sin x .

Considering this, what is tan value?

Tangent or **Tan** function is defined as a**value** (or the ratio) obtained by dividing the Opposite Sideby Adjacent Side with reference to angle being measured in a RightAngled Triangle. It also is same as Sin(deg)/Cos(deg).

Beside above, what is CSC equal to? Cosecant (**csc**) - Trigonometryfunction In a right triangle, the cosecant of an angle is thelength of the hypotenuse divided by the length of the oppositeside. In a formula, it is abbreviated to just'**csc**'.

Similarly, you may ask, what is tan A?

In any right triangle, the tangent of an angle is thelength of the opposite side (O) divided by the length of theadjacent side (A). In a formula, it is written simply as'**tan**'. Often remembered as "TOA" - meaning Tangent isOpposite over Adjacent. See SOH CAH TOA. **tan**.

Why is it called tangent?

As it passes through the point where the **tangent**line and the curve meet, **called** the point of tangency, the**tangent** line is "going in the same direction" as the curve,and is thus the best straight-line approximation to the curve atthat point. The word "**tangent**" comes from the Latin tangere,"to touch".
