Introduction
Radians and degrees are units of measurement used in geometry and trigonometry. It is essential to know how to convert between radians and degrees for solving various mathematical problems. This article is designed to provide you with a step-by-step guide, video tutorial, infographic, real-life examples, calculator tool, and common mistakes to avoid while converting radians to degrees.
Step-by-step guide
The conversion formula for radians to degrees is simple. One radian is equal to 360 divided by 2π degrees. So to convert radians to degrees, multiply the radian measure by 180 and divide by π. The formula can be expressed as:
Degrees = Radians × (180/π)
For example, if you want to convert 2 radians to degrees:
Degrees = 2 × (180/π) = 114.59 degrees
