The tangent of x is defined to be its sine divided byits cosine: 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 avalue (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 tangentline and the curve meet, called the point of tangency, thetangent 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".

## What is cos in math?

In a right angled triangle, the cosine of anangle is: The length of the adjacent side divided by the length ofthe hypotenuse. The abbreviation is cos. cos(θ)= adjacent / hypotenuse. Teacher

## How fo you find the area of a triangle?

To find the area of a triangle,multiply the base by the height, and then divide by 2. The divisionby 2 comes from the fact that a parallelogram can be divided into 2triangles. For example, in the diagram to the left, thearea of each triangle is equal to one-half thearea of the parallelogram. Teacher

## How do you remember Sin Cos values?

Divide your sine values by the cosinevalues to fill the tangent column. Simply speaking,tangent = sine/cosine. Thus, for every angle,take its sine value and divide it by its cosine valueto calculate the corresponding tangent value. To take30° as an example: tan 30° = sin 30° /cos 30° = (√1/2) / (√3/2) =1/√3.

## How do I find the length of a triangle?

The hypotenuse is the longest side of a righttriangle, and is thus located opposite the right angle. So,if you know the lengths of two sides, all you have to do issquare the two lengths, add the result, then take the squareroot of the sum to get the length of thehypotenuse. Teacher

## How do you find the SEC?
