Solving Trigonometric Equation algebraically | Proving problems on Trigonometric Identities
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 (4)
00:28 solving trigonometric identities procedure
00:43 consider LHS of the trigonometric equation
00:55 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.
01:42 consider RHS of the trigonometric equation
01:58 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
02:28 a squared minus b square formula
02:55 LHS & RHS of the trigonometric equation are equal.
Hence,trigonometric identity is solved.
