# What is the right triangle definition of the sine function?

**Sine Function**in

**Right Triangles**. It

**means**that

**sine**is the ratio of the opposite side divided by the hypotenuse.

Herein, what is the sin of a right triangle?

**Sine** (**sin**) function - Trigonometry. In a **right triangle**, the **sine** of an angle is the length of the opposite side divided by the length of the hypotenuse.

Secondly, how do you convert sine to degrees? To supply an angle to **SIN** in **degrees**, multiply the angle by PI()/180 or use the RADIANS function to **convert** to radians. number - The angle in radians for which you want the **sine**.

Hereof, what is the sine of an angle?

In mathematics, the **sine** is a trigonometric function of an **angle**. The **sine** of an acute **angle** is defined in the context of a right triangle: for the specified **angle**, it is the ratio of the length of the side that is opposite that **angle** to the length of the longest side of the triangle (the hypotenuse).

What is the sine function equation?

Let's start with the basic **sine function**, f (t) = **sin**(t). This **function** has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This **function** has a period of 2π because the **sine** wave repeats every 2π units.
