In this paper we show that if a finite set of at least two points in the plane has a diameter less than 3, then there is a unit circle passing through exactly two points of the set. I conjecture that if the diameter of the point-set is between 3 and 2, then the same statement ...

This paper shows that the inverse chirp z-transform (ICZT), which generalizes the inverse fast Fourier transform (IFFT) off the unit circle in the complex plane, can also be used with chirp contours that perform partial or multiple revolutions on the uni
What are the trig functions and how do they relate to the unit circle? The primary trig functions are sine, cosine and tangent. On the unit circle, sine corresponds to the y-value, and cosine to the x-value of points. The unit circle provides a geometric representation of these functions...
The three key trigonometry functions applied to an angle are cosine, sine, and tangent. These are the three functions that we apply to find the coordinates of a given angle on the unit circle. Using all the information above, you will be able to find the cosine and sine values of the ...
To determine the cosecant of θ on the unit circle: From the center of the circle draw the radius corresponding to the angle θ. Draw tangent lines to the circle at points (0,1) and (0,-1). Extend the radius from Step 1 so that it intersects one of those tangents. The distance ...
Like all functions, the sine function has an input and an output. Its input is the measure of the angle; its output is the y-coordinate of the corresponding point on the unit circle.The cosine function of an angle tt equals the x-value of the endpoint on the unit circle of an arc ...

Thus, for all M, the points were on the same chirp contour, i.e., a 360° segment of a logarithmic spiral. This was inspired by the way the FFT adds new points when the transform size is doubled (in the FFT case, however, the points are always on the unit circle). Figure 2 ...
