In trigonometry sin cos and tan values are the primary functions we consider while solving trigonometric problems. A very easy way to remember the three rules is to to use the abbreviation SOH CAH TOA.

The tangent of the angle the length of the opposite side. Tan2x 2 tanx 1. Before we can use trigonometric relationships we need to understand how to correctly label a right-angled triangle. The length of the adjacent side.

The cotangent of x is deﬁned to be the cosine of x divided by the sine of x. Introduction SinCosTan is a very basic form of trigonometry that allows you to find the lengths and angles of right-angled triangles. That the real part of the left hand side equals the real part of the right hand side is an angle addition formula for cosine. Y x 3 x x ln log.

Sin and Cos are basic trigonometric functions along with tan function in trigonometry.

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse whereas the cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The tangent of x is deﬁned to be its sine divided by its cosine. These trigonometry values are used to measure the angles and sides of a right-angle triangle.

The Greeks focused on the calculation of chords while mathematicians in India created the earliest-known tables of values for trigonometric ratios also called trigonometric functions such as sine.
