In this math tutorial we prove trigonometric identities, solve trigonometric equations and Verify Trigonometric Identities.We use Quotient Identities , Reciprocal Identities, and the Pythagorian Identities to solve problems on trigonometric identities.

Solve Trigonometric Equations with Trigonometric Identities

Defination of an Identity:

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

Trigonometric Identities defination:

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.

00:02 Q5. Prove the trigonometric equations using trigonometric identities, where the angles involved are acute angles for which the expressions are defined

00:04 q5 (3)

00:30 How to solve Trigonometric equations using Trigonometric identities

00:52 Quotient Identities

cot A = cos A / sin A. tan A = sin A/cos A.

02:21 solving Trigonometric identities

04:03 a cube minus b cube formula

Expanding a cube

04:40 Use Pythagorian Identity

sin squared theta plus cos squared theta = 1

05:21 Reciprocal Identity.

The ratios cosec A, sec A and cot A are respectively, the reciprocals of the ratios sin A, cos A and tan A

sec A = 1/cos A. cosecA = 1/sin A.
