Creating a unit circle diagram with both degree and radian measures helps cement these relationships in memory. Mark the standard angles around the circle, noting how the radian measures relate to ...

Why Is the Unit Circle Important? A unit circle defines right triangle relationships known as sine, cosine and tangent. These relationships describe how angles and sides of right triangles relate to ...

In a unit circle, any line that starts at the center of the circle and ends at its perimeter will have a length of 1. So, the longest side of this triangle will have a length of 1. The longest side of ...

Part of that is the way it's taught. Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions.
