is based on the study of right-angled triangles. This is a form of geometry that developed out of the study of the stars. It is also concerned with the relationships that exist between the sides and angles of triangles, and their measurement. comes in two forms, spherical and plane. Spherical is the study of curved triangles lying on th ...

... Even though there are six types of trigonometric functions, three of them are commonly used ratios are sine, cosine, and tangent. The other three are cotangent, secant, and consecant. Here is an example of how trigonometric functions of a general angle work. The angle, as shown in the diagram, is measured by usually showing the Greek letter theta, 0. The sine is the ratio of o, which is the length of the side opposite 0, to h, which is the length of the hypotenuse. The cosine is the rati ...
