**Trig Unit Circle Why? Physics Forums**

15/04/2017Â Â· Ok- I am teaching trigonometry to low level students right now and I am trying to figure out why they need to know the unit circle. Are there some interesting things they can learn about by using a unit circle?... The trigonometric functions sine and cosine are defined in terms of the coordinates of points lying on the unit circle x 2 + y 2 = 1. Start by constructing the ray from the origin at angle Î¸ (measured counter-clockwise from the positive x-axis).

## How To Learn The Unit Circle

### What I have attempted to draw here is a unit circle. And the fact I'm calling it a unit circle means it has a radius of 1. So this length from the center-- and I centered it at the origin-- this length, from the center to any point on the circleâ€¦

- When I took Trigonometry it was based upon the unit circle drawn on an x/y graph. From it were derived all of the Trigonometric functions - Sine, cosine, tangent, cosecant, secant, and cotangent That was in 1971 and I still remember how the instru...
- Sine, Cosine, Tangent and the Unit Circle Let x be an angle measured in radians drawn in standard position together with a unit circle. The radian measure of x is the length of the arc on the unit circle subtended by the angle.
- Angles and the Unit Circle can be a tough one. Not because mastering the Special Right Triangles is difficult but because you are relying on their Geometry Teacher to have done an excellent job of establishing that mastery.
- After the warm-up problem, I presented page 3 of the Flipchart_Building the Unit Circle to quickly introduce what a Unit Circle is. I just wanted to emphasize that this is a special circle â€¦
