06:44 Procedure for solving Trigonometric equations
06:48 consider LHS of the trigonometric equations
07:08 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
Quotient Identity
cot A = cos A / sin A.
07:42 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
09:21 trigonometric equation is proved

09:46 Q5. Prove the trigonometric equations using trigonometric identities, where the angles involved are acute angles for which the expressions are defined
09:49 q5 (4)
09:50 solving trigonometric identities procedure
09:59 consider LHS of the trigonometric equation
10:13 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.
11:02 consider RHS of the trigonometric equation
11:21 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
11:43 a squared minus b square formula
12:16 LHS & RHS of the trigonometric equation are equal.
Hence,trigonometric identity is solved

12:54 Q5. Prove the trigonometric identities, where the angles involved are acute angles for which the expressions are defined
12:58 q5 (8).
13:02 Procedure for solving Trigonometric equations
13:06 Consider LHS of the trigonometric equation
14:47 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.
cosec A = 1 / sin A.
15:06 Use Pythagorian Identity
Cosecant squared theta minus cot squared theta = 1
15:17 secant squared theta minus tan squared theta = 1
15:34 Simply the trigonometric expression.
15:37 LHS is RHS of the trigonometric equation.Trigonometric equation is proved.
