00:02 1. Express the trigonometric ratios sin A, sec A and tan A in terms of cot A.

00:24 Defination of trigonometry Identities

An equation is called an identity when it is true for all values of the variables involved.

An equation involving trigonometric ratios of an angle is called a trigonometric identity, if it is true for all values of the angle(s) involved

00:30 Pythagorean Identities
