The program will show you the x, y, degree, and. To use this program just type in the number of the point and hit ENTER to view the value of that point. From there, the program assigns each point a number. Designed for Year 10A Maths in Victoria, Australia, but could be adapted for use elsewhere. The following diagram is a unit circle with \(24\) points equally space points plotted on the circle. The Unit Circle program is a simple program that displays the unit circle onto the graph screen of the calculator. Introduction to the unit circle and sin/cos defined in terms of the unit circle. This will be studied in the next exercise. In other words, the center is put on a graph where the X and Y axes cross. Further within the first quadrant at the angles of 0, /6, /4, /3, /2 are the standard values, which are applicable to the trigonometric ratios. The unit circle is a circle with a radius of one unit with its center placed at the origin. And the unit circle is divided into four quadrants at angles of /2. Since the circumference of the unit circle is \(2\pi\), it is not surprising that fractional parts of \(\pi\) and the integer multiples of these fractional parts of \(\pi\) can be located on the unit circle. The unit circle represents a complete angle of 2 radians.
