How to Convert Degrees into Radians

Description

This video gives an in-depth tutorial on how to convert degrees to radians, and how to convert radians back into degrees. Many examples are provided and explanations are set up in an easy to understand fashion.

Overview

Degrees are a very common thing to see – they are used in solving angles, and sometimes used in solving trangle problems. However, degrees are only a unit, and like any unit they can be converted to another one. Degrees are converted to radians – radians are used with sine, cosine, and tangent. The easiest way to remember radians is to memorize the most common degrees and their conversion into radians:

0 degrees = 0 radians

30 degrees = pi/6 radians

45 degrees = pi/4 radians

60 degrees = pi/3 radians

90 degrees = pi/2 radians
