## 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 Example 1:**

Find the sine value if the θ = 45°

**Solution:**

Given θ = 45°

sin45° = 1 / √2

= 0.71

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

- θ = 60°
- θ = 150°
