doi:10.1016/0012-365X(86)90011-7Every three of n points in the plane determine a circle. The maximum number f(n) of congruent circles is determined for n ⩽ 7: f(3) = 1, f(4) = f(5) = 4, f(6) = 8, f(7) = 12.HeikoHarborthandIngridMengersenSDOSDiscrete Mathematics...
题目意思是，下面坐标表示的点不在单位圆上。其实就是验证一下横坐标和纵坐标的平方和是不是为1，如果是1，那就在单位圆上，如果不是1就不在单位圆上。结果得出应该选d
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...

How do I find cosecant with the unit circle? 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...
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 ...

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
The line {eq}y = \frac{1}{2}x {/eq} intersects the unit circle at two points. What are they? Round to two decimal places. Unit circle: definition and intersection with a line: Definition: We called unit circle to the circle with radius 1 center...
