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.

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. There are loads of trigonometric identities, but the following are the ones you're most likely to see and use. Notice how a "co- something " trig ratio is always the reciprocal of some "non-co" ratio.
