How to Find Exact Values of Tangent and Cotangent Using the Unit Circle and Special Triangles Step 1: Identify whether we are finding {eq}\tan\theta {/eq} or {eq}\cot\theta, {/eq} and identify what our angle {eq}\theta {/eq} is. Step 2: Find the poin...
It can be shown that the trigonometric functions of an angleθin standard position can be obtained from the coordinates of the point of intersection of the terminal side ofθand the unit circle. If a general point on the terminal side is given instead, an extra computation might ...
For the second-order response surface model on a circle with qualitative factors, the corresponding exact D-optimal designs are useful in obtaining precise estimates of the model parameters in practice. According to the construction method proposed in Section 4.2, it is convenient to construct exact...
One ground for suspicion that an approximation method is loosely geometrical is that the values leap on both sides of the true value, above and below. Of course, this will not always be the case. The anthyphairetic methods for square roots shift on both sides, but we also understand clearl...
7.3), we explore the stability properties of the signed barcodes by considering a family of point sets sampled from the unit circle with an increasing amount of noise. In the final experiment (Sect. 7.4), we apply our methods in the context of two-parameter clustering. Before getting to ...

a meridian (a great circle), if we draw an arc from the tip of the pointer’s shadow on the sundial at Alexandria round to the base of the pointer, this arc will be a section of the great circle in the sundial’s bowl, since the sundial’s bowl is located below a great circle”...
