This project is meant to help students in both remembering the unit circle and also understanding it.
INSTRUCTIONS:
There are two worksheets included in this project:
- Unit circle project background information.
- The Unit Circle.
Your project must be neat. Your angle measurements must be precise and use your creativity in presenting your project.
UNIT CIRCLE PROJECT: BACKGROUND INFORMATION
The unit circle is a circle centered at origin (the point ____, ____) with a radius equal to ____. Since the equation of the circle is (x – h)2 + (y – k)2 = r2 , where (h, k) is the center of the circle and r is the radius. Then the equation of the unit circle is _____________________________. The circumference of the circle is found by using the formula _________________________, because the radius of the unit circle is equal to ___________, so the circumference of the unit circle is ______________.
When measured in degrees, one full revolution of a circle is equal to ____________degrees. If we split the circle into 4 equal parts, then at each corner the angles go up by __________ (360 divided by 4). If we split the circle into 8 equal parts, then from one point to another we would need to add by ____________.
