Unit Circle Table Of Values In Radians

What is unit circle table of values in radians?

The unit circle table of values in radians is a tool used in trigonometry to represent the relationship between the angles and the values of the sine, cosine, and tangent functions. It consists of a circle with a radius of 1 unit, centered at the origin of a coordinate plane. The angles, measured in radians, are denoted around the circumference of the circle. The table of values provides the corresponding sine, cosine, and tangent values for each angle.

What are the types of unit circle table of values in radians?

There are two types of unit circle tables of values in radians: the complete unit circle and the half unit circle. The complete unit circle includes angles from 0 radians to 2π radians (or 0 to 360 degrees), while the half unit circle includes angles from 0 radians to π radians (or 0 to 180 degrees). Both types of tables provide the same sine, cosine, and tangent values for their respective angles.

Complete unit circle
Half unit circle

How to complete unit circle table of values in radians

To complete a unit circle table of values in radians, follow these steps:

01
Draw a circle with a radius of 1 unit on a coordinate plane.
02
Divide the circle into 360 equal divisions (for the complete unit circle) or 180 equal divisions (for the half unit circle).
03
Assign each division an angle, starting from 0 radians and increasing in a counterclockwise direction.
04
Calculate and record the corresponding sine, cosine, and tangent values for each angle.
05
Round the values to the desired precision, such as two decimal places.
06
Label the angles and their corresponding values in the table.

Easy to use -- several format/file extension options for saving and ability to link with cloud and sharing platforms makes this so versatile. Having the option to save a filled form as a template is very helpful. The customization and array of options is allowing me to complete tasks, for which I previously needed multiple programs.
