In trigonometry, sin cos and tan values are the primary functions we consider while solving trigonometric problems. These trigonometry values are used to measure the angles and sides of a right-angle triangle. Apart from sine, cosine and tangent values, the other three major values are cotangent, secant and cosecant. It is easy to memorise the values for these certain angles. The trigonometric values are about the knowledge of standard angles for a given triangle as per the trigonometric ratios sine, cosine, tangent, cotangent, secant and cosecant. The three ratios, i. Suppose, ABC is a right triangle, right-angled at B, as shown in the figure below:. Put your understanding of this concept to test by answering a few MCQs.

Logically, mathematical identities are tautologies; that is, they are expressions which restate the same expression in a different way. In other words, the identities allow you to restate a trig expression in a different format, but one which has the exact same value.

The fact that you can take the argument's "minus" sign outside for sine and tangent or eliminate it entirely for cosine can be helpful when working with complicated expressions.

In trigonometry, sin, cos, and tan are the basic trigonometric ratios used to study the relationship between the angles and sides of a triangle especially of a right-angled triangle. Pythagoras worked on the relationship between the sides of a right triangle through the Pythagorean theorem while Hipparcus worked on establishing the relationship between the sides and angles of a right triangle using the concepts of trigonometry. Sin, cos, and tan formulas in trigonometry are used to find the missing sides or angles of a right-angled triangle.

There are loads of trigonometric identities, but the following are the ones you're most likely to see and use. Enter email id Enter mobile number. Notice in particular that sine and tangent are odd functions , being symmetric about the origin, while cosine is an even function , being symmetric about the y -axis. Need a custom math course?
