## Trigonometric Values Table

Trigonometry Values: The trigonometric table is a table of values for the trigonometric functions sine, cosine, and tangent. The table is typically organized in a grid, with the angles in radians on the horizontal axis and also the corresponding trigonometric function values on the vertical axis.

## Trigonometric Ratios

The trigonometric ratios are the ratios of the length of the sides of a right triangle to the length of the hypotenuse. There are six trigonometric ratios: sine, cosine, tangent, cotangent, secant, and also cosecant.

## Values of Trigonometric Ratios

There are six basic trigonometric ratios, which are also known as basic angles. They are:

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and also cosecant (csc).

Each of these angles can be represented by a number, which is known as its radian measure. Therefore the radian measure is simply the number of complete rotations (or revolutions) that the angle has made around the unit circle.

The radian measure of a particular angle can be calculated by using the following formula:

radian measure = (length of arc)/(radius of circle)

The length of the arc is measured in radians, and the radius of the circle is always 1.

For example, if an angle has a radian measure of 3.14, that means it has made 3.14 complete rotations around the unit circle.

The six basic trigonometric ratios can calculated using the following formulas:

- sine = sin(angle) = (length of arc)/(radius of circle)
- cosine = cos(angle) = (radius of circle)/(length of arc)
- tangent = tan(angle) = (length of opposite side)/(length of adjacent side)
- also cotangent = cot(angle) = (radius of circle)/(length of adjacent side)

## Sign of Trigonometric Functions

The trigonometric functions usually denoted by the letters sin, cos, tan, cot, sec, and also csc.

## Trigonometry Ratios Formula

In mathematics, the trigonometry ratios are a set of six ratios that are used to calculate the angles and distances of points on a triangle. The trigonometry ratios also known as the trigonometric functions.

## Tricks to Remember the Trigonometric Values

There are a few tricks that can used to remember the trigonometric values. One is to use the acronym “SOH CAH TOA.” This stands for:

also Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent
