The Unit Circle Lesson 13-2 Objective: Students will use reference angles and the unit circle to find the to find the sine and cosine values of an angle in Standard Position UNIT CIRCLE The "Unit Circle" is a circle with a radius of 1. Because the radius is 1, we can directly measure sine, cosine, and tangent.Take for example polynomial 5x2 − 6x + 5 5 x 2 − 6 x + 5. It's easy to check it has roots 3 5 ± 4 5i 3 5 ± 4 5 i, which are both on the unit circle, but neither is a root of unity. However, if you restrict your attention to monic integer polynomials, then this is indeed correct: it's a result due to Kronecker, and you can see a few proofs ...The Unit Circle. The point of the unit circle is that it makes other parts of the mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x. Working from this, you can take the fact that the tangent is defined as being tan(θ ...

The unit circle is a circle with a radius of 1 and is divided into 4 quadrants. Having a radius of 1 makes the unit circle a great tool for measuring lengths and angles using sin, cos and tan. It is important that students understand that the unit circle forms part of trigonometry and that the trigonometric ratios previously studied in VCMMG346 ...The printable unit circle worksheets are intended to provide high school practice in using the unit circle to find the coordinates of a point on the unit circle, find the corresponding angle measure, determine the six trigonometric ratios and a lot more.

All three angles are 60 degrees (pi/3). Cut it into two right triangles and you get an angle of 30 degrees (pi/6). That also means that the opposite side is going to be exactly half of the hypotenuse. In a unit circle that means that sin=1/2. From there we can work out cos=sqrt3/2.Preparation.
