## What is the difference between sinus and cosinus?

Law of Sine is used to calculate the length of unknown side of that triangle, whose one side and two angles are known. Whereas the law of Cosine is used to calculate the side of that triangle, whose one angle and two sides are known.

**How do you calculate sinus and cosinus?**

In any right angled triangle, for any angle:

- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.

### What is sinus cosinus Tangens?

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: “Opposite” is opposite to the angle θ “Adjacent” is adjacent (next to) to the angle θ

**What is the meaning of cosinus?**

n. A function of an angle expressed as the ratio of two of the sides of a right triangle that contains that angle; the sine, cosine, tangent, cotangent, secant, or cosecant.

#### Does sin go with CSC?

The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

**Is cotangent Cos over sin?**

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .

## How are sin and csc related?

The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

**Is Arccsc a sin?**

The functions are usually abbreviated: arcsine (arcsin), arccosine (arccos), arctangent (arctan) arccosecant (arccsc), arcsecant (arcsec), and arccotangent (arccot)….Math2.org Math Tables:

sin(q) = opp/hyp | csc(q) = 1/sin(q) |
---|---|

tan(q) = sin(q)/cos(q) | cot(q) = 1/tan(q) |
