No CommentsHow 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
