# How do you calculate sinus and cosinus?

## How do you calculate sinus and cosinus?

In any right angled triangle, for any angle:

1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.
2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.

## How do you calculate cosinus?

Starts here1:19How to Calculate Cosine Angles Given a Hypotenuse & an AngleYouTubeStart of suggested clipEnd of suggested clip58 second suggested clipAnd kind of go from there. So the idea here is the hypotenuse is canceled. So you have the adjacentMoreAnd kind of go from there. So the idea here is the hypotenuse is canceled. So you have the adjacent leg equal to the hypotenuse times the cosine of the angle. Now. Since you’re given the hypotenuse.

What is value of tan30?

What is the exact value of tan 30 degrees? Tan 30 degree is equal to 1/√3 and its exact value is 0.57735.

How do you find a hypotenuse?

The hypotenuse is termed as the longest side of a right-angled triangle. To find the longest side we use the hypotenuse formula that can be easily driven from the Pythagoras theorem, (Hypotenuse)2 = (Base)2 + (Altitude)2. Hypotenuse formula = √((base)2 + (height)2) (or) c = √(a2 + b2).

### What is the complement of TAN 30?

For example, as 30° + 60° = 90°, 60° is called the complement of 30° and conversely, 30° is called the complement of 60°.

### What is the value of cot 60 degree?

1√3
The exact value of cot(60) is 1√3 .

What is SEC math trig?

In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec(θ) = hypotenuse / adjacent. It is not commonly used, and is equal to 1/cosine.

What is Cotangent trigonometry?

Definition of cotangent 1 : a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the leg opposite.
