I've been told that the infinitesimal change in coordinates x and y as you rotate along a hyperbola that fits the equation b(dy)^2-a(dx)^2=r takes the form δx=bwy and δy=awx, where w is a function of the angle of rotation (I'm pretty sure it's something like sinh(theta)...
In trigonometry, two angles that, when added together, equal {eq}90^{\circ} {/eq} or {eq}\frac{\pi}{2} {/eq} radians are said to be complementary angles. To find the complement of an angle, the angle is subtracted from {eq}90^{\circ} {/eq} (if using degrees) or {eq}\fra...

Trigonometry is one of the most interesting concepts of mathematics. In trigonometry, we come across various methods all incorporating three major or fundamental functions,Sine, Cosine and Tangent, which are generally used to determine theanglesandlengthof the right-angled triangle. Before we start ou...
