Formula Explained

The sine of an angle in degrees is calculated using the following formula:

sin(x°) = sin(x × π/180)

Where:

x is the angle in degrees
π (pi) is approximately 3.14159265359

This formula converts the angle from degrees to radians before calculating the sine value.

Worked Examples

Example 1: Calculating sin(30°)

Using the formula:

sin(30°) = sin(30 × π/180) ≈ sin(0.5236) ≈ 0.5

The sine of 30 degrees is approximately 0.5.

Example 2: Calculating sin(90°)

Using the formula:

sin(90°) = sin(90 × π/180) ≈ sin(1.5708) ≈ 1

The sine of 90 degrees is exactly 1.

Frequently Asked Questions

What is the sine function?

The sine function is a trigonometric function that relates the angle of a right triangle to the ratio of the length of the opposite side to the hypotenuse. It's periodic and oscillates between -1 and 1.

Why do we need to convert degrees to radians?

Most programming languages and calculators use radians for trigonometric functions. The conversion from degrees to radians is necessary to use these functions correctly.

What are the common angles in degrees?

Common angles in degrees include 0°, 30°, 45°, 60°, 90°, 180°, 270°, and 360°. These angles have exact sine values that are often used in calculations.
