# How do you find the sine cosine and tangent of an angle?

## How do you find the sine cosine and tangent of an angle?

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 remember Sin Cos tan and trigonometry?

The sine, cosine, and tangent ratios in a right triangle can be remembered by representing them as strings of letters, for instance SOH-CAH-TOA in English: Sine = Opposite ÷ Hypotenuse. Cosine = Adjacent ÷ Hypotenuse. Tangent = Opposite ÷ Adjacent.

How do you know if its sin cos or tan?

The sine of an angle is equal to the side opposite the angle divided by the hypotenuse. The cosine of an angle is equal to the side adjacent to the angle divided by the hypotenuse. The tangent of an angle is equal to the side opposite the angle divided by the side adjacent to the angle.

What does sine, cosine, and tangent actually do?

In this career, sine, cosine, and tangent are sometimes used to determine the size of large sea creatures from a distance, and also to calculate light levels at certain depths to see how they affect photosynthesis. There are dozens of careers that use trigonometry in their daily tasks.

### What is the relationship between sine and cosine?

The relationship between the cosine and sine graphs is that the cosine is the same as the sine — only it’s shifted to the left by 90 degrees, or π /2. The trigonometry equation that represents this relationship is Look at the graphs of the sine and cosine functions on the same coordinate axes,…

### How do you find the sine of a triangle?

The trigonometric function sine, like the cosine and the tangent, is based on a right-angled triangle. In mathematics, you can find the sine of an angle by dividing the length of the side opposite the angle by the length of the hypotenuse.

What is the difference between tangent and sine?

tangent | sine |. is that tangent is (geometry) a straight line touching a curve at a single point without crossing it there while sine is (trigonometry|mathematics) in a right triangle, the ratio of the length of the side opposite an angle to the length of the hypotenuse.
