# Sine Calculator

'**Sine Calculator**' is an online tool that helps to calculate the sine value for a given angle theta. The** sine** of an angle is a trigonometric function that is denoted by sin x, where x is the angle in consideration. In a right-angled triangle, the ratio of the perpendicular and the hypotenuse is called the sine function.

## How to Find Sine Calculator?

The sine function is defined as the ratio of the length of the perpendicular to that of the length of the hypotenuse in a right-angled triangle. The sign is a trigonometric function of an angle. It is denoted as sinθ, where θ is the angle between the two sides.

**Solved Examples on Sine Calculator**

**Example 1:**

Find the sine value if the θ = 45°

**Solution:**

Given θ = 45°

sin 45° = 1 / √2

= 0.71

**Example 2:**

Find the sine value if the θ = 90°

**Solution:**

Given θ = 90°

sin 90° = 1

= 1

**Example 3:**

Find the sine value if the θ = 30°

**Solution:**

Given θ = 30°

sin 30° = 1/2

= 1/2

Similarly, you can try the calculator to find the sine values for the following:

- θ = 60°
- θ = 150°
