How to Plot a Radian Table

Within mathematics, there are two primary units for measuring angles: degrees and radians. While the former is arguably more common, the latter is also useful, particularly in trigonometry. A good way to understand the relationship between degrees and radians is by making a radian "table" to visually organize corresponding radian and degree values. This way, you will have your own reference to use whenever you need to make a snap conversion between the two units.

Instructions

- 1
  Make a list of common degree values for which you want to have radian equivalents. For example, you might want radian values for 30, 45, 60, 90, 180 and 360 degrees.
- 2
  Convert these values into radians, keeping in mind the conversion factor 2π radians = 360 degrees. Therefore, 180 degrees--half of 360--would be π--2π/2--radians, 90 π/2 radians and so forth.
- 3
  Draw out the table and input your values into them. No matter how detailed you make your radian table, it will need to have two columns: one for degrees, one for radians. Your number of rows will depend on how many degree values you chose to convert. Enter your degree and radian values, double-checking for accuracy before you stop work.
