# What is sinus divided by Cosinus?

## What is sinus divided by Cosinus?

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .

What is sinus cosinus Tangens?

The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated “tan”) is the ratio of the length of the side opposite the angle to the length of the side adjacent.

How do you calculate sinus and cosinus?

Sin, Cos and Tan

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.

### What is the meaning of SOH CAH TOA?

“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) (3)

Why is tan called tangent?

Tangent comes from the latin tangere, the verb meaning “to touch”. A line tangent to a circle intersects it at exactly one point.

What is tan used for?

Tangent is a trigonometric ratio comparing two sides of a right triangle. Tangent is usually shortened to tan but is pronounced tangent. This function can be used to determine the length of a side of a triangle when given at least one side of the triangle and one of the acute angles.

## What is the value of tan A?

Deriving the Value of Tan Degrees

Angles (in degrees) 45°
Sin 0 1 2
Cos 1 1 2
tan 0 1

Why is tangent important?

One reason that tangents are so important is that they give the slopes of straight lines. Consider the straight line drawn in the x-y coordinate plane. The point B is where the line cuts the y-axis. We can let the coordinates of B be (0,b) so that b, called the y-intercept, indicates how far above the x-axis B lies.

Where is tan positive?

In the first quadrant, the values for sin, cos and tan are positive. In the second quadrant, the values for sin are positive only. In the third quadrant, the values for tan are positive only. In the fourth quadrant, the values for cos are positive only.
