given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trigonometric ratios are basic tools used in trigonometry to study right triangles, either to find sides or angl...
How to Find Trigonometric Ratios Given a Right Triangle: Example 1 Given the right triangle depicted below, calculate all six of the trigonometric ratios of {eq}\theta {/eq}. Step 1: Identify the sides of the right triangle and their lengths. ...
How to Find Trigonometric Ratios from a Point on the Unit Circle: Example 1 What is the sine, the cosine, and the tangent of the angle of rotation at the point on the unit circle with coordinates of {eq}\displaystyle \left(\frac{\sqrt{2}}{2},-\frac{\sqrt{2}}{2} \right...
To find the angle between two curves intersecting in a point, we will calculate the angle between the tangent vectors to the curve at the common point. If we are interested in the acute angle of intersection, then we will take the positive argument of inverse cosine function: {eq}\...
To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenus...

We define a cost function that considers the stresses in the servo, the angular momentum in the servo joint, which is related to the gear tooth stress, and the mass of the leg, displayed in Supplementary Fig. 3. The particle swarm optimization (PSO) is used to find the best set of ...
number by the hypotenuse length. The result is the length of the adjacent side, and it has the same unit as the hypotenuse. The use of sine (opposite/hypotenuse) and tangent (opposite/adjacent) functions to find the distance of "Y" is similar to the method used with the cosine function...
