If a right triangle is placed in a unit circle in the cartesian coordinate plane, with hypotenuse, base, and altitude measuring 1, x, y units respectively, then the unit circle identities can be given as,$sin\;(\theta) = y$ $cos\;(\theta) = x$ $tan\;(\\theta) = \frac{sin\;...
A unit circle is a circle with a radius of one unit. Generally, a unit circle is represented in thecoordinate planewith its center at the origin. The equation of the unit circle of radius one unit and having the center at (0, 0) is x2+ y2= 1. Further, the unit circle has appli...
A circle is centered at the origin (0,0) and has a radius of 4 units. a. Which points on the circle have an x-coordinate of 1? b. Which points on the circle have a y-coordinate of 3? c. Write an equation for the graph of this circle. ...
The unit circle is important because it allows us to calculate the cosine, sine, and tangent of an angle less than 360 degrees or 2π with ease. Can you use degrees on the unit circle instead of radians? Yes! Both degrees and radians are equally useful units to use to measure angles ...

To define the remaining functions, we will once again draw a unit circle with a point (x,y)(x,y) corresponding to an angle of tt, as shown in Figure 1. As with the sine and cosine, we can use the (x,y)(x,y) coordinates to find the other functions....

Actually we use polar coordinates throughout, in a rotating frame with canonical units of length and time. In this frame, the larger primary is at the origin, while the smaller primary is at (1,0). We are especially interested in the motion near the unit circle, (r=1). This type of...
