science space and astronomy# What is tangent in terms of sine and cosine?

Last Updated: 28th June, 2020

**tangent**of x is defined to be its

**sine**divided by its

**cosine**:

**tan**x =

**sin**x

**cos**x . The cotangent of x is defined to be the

**cosine**of x divided by the

**sine**of x: cot x =

**cos**x

**sin**x .

Thereof, what does Sine cosine and tangent mean?

**Sine**, **Cosine and Tangent** are the mainfunctions used in Trigonometry and are based on a Right-AngledTriangle. "Opposite" is opposite to the angle θ "Adjacent" isadjacent (next to) to the angle θ "Hypotenuse" is the longone.

Beside above, what is tangent equal to? In any right triangle, the **tangent** of an angle isthe length of the opposite side (O) divided by the length of theadjacent side (A). In a formula, it is written simply as'**tan**'. Often remembered as "TOA" - meaning Tangent isOpposite over Adjacent.

how do you find sine cosine and tangent?

**In any right angled triangle, for any angle:**

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

What is cot in terms of sin?

In a right triangle, the **cotangent** of an angle isthe length of the adjacent side divided by the length of theopposite side. In a formula, it is abbreviated to just'**cot**'. **cot**. x.
