## How do you express trigonometric ratios?

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec)….

Trigonometric Ratios
Sin θ Opposite Side to θ/Hypotenuse
Cos θ Adjacent Side to θ/Hypotenuse
Tan θ Opposite Side/Adjacent Side & Sin θ/Cos θ
Cot θ Adjacent Side/Opposite Side & 1/tan θ

## What are the 12 trigonometric ratios?

They are sine, cosine, tangent, cosecant, secant, and cotangent. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. All the fundamental trigonometric identities are derived from the six trigonometric ratios.

What are the 5 trigonometric ratios?

Review all six trigonometric ratios: sine, cosine, tangent, cotangent, secant, & cosecant.

What are the 6 trigonometric ratios?

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

### Why there are only 6 trigonometric ratios?

There are only 6 trigonometric ratios because only 6 ratios can define ratios of all sides. For example, If you want ratio between perpendicular and hypotenuse there is sin. If you want ratio between perpendicular and base there is tan.

### What are the 3 trigonometric ratios?

The three trig ratios in question are sine (sin), cosine (cos) and tangent (tan). In this article however we are going to concentrate for the most part on sine. The reference angle in a right triangle is, in general, given the symbol θ (theta).

Is it possible to have eight trigonometric ratios?

(It’s well known that you can shake a stick at a maximum of 8 trig functions.) The familiar sine, cosine, and tangent are in red, blue, and, well, tan, respectively.

What is reciprocal trigonometric ratios?

There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).

## What kind of triangle can we define the six trigonometric ratios?

a right triangle
The correct answer is 19.47°. The six trigonometric functions are defined as ratios of sides in a right triangle. Their values depend only on the angle and not on any particular right triangle. A good way to remember the definitions of sine, cosine, and tangent is with the memory device sohcahtoa.

## What are the six trigonometric ratios?

What are some examples of trigonometric ratios?

From this table, we can find the value for the trigonometric ratios for these angles. Examples are: Sin 30° = ½; Cos 90° = 0; Tan 45° = 1 Trigonometry Applications. Trigonometry is one of the most important branches of mathematics. Some of the applications of trigonometry are: Measuring the heights of towers or big mountains

What is trigonometry in geometry?

In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles. Note: Opposite side is the perpendicular side and the adjacent side is the base of the right-triangle.

### What is the ratio of sides of a right triangle?

The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle. The three sides of the right triangle are: Hypotenuse (the longest side) Perpendicular (opposite side to the angle)
