00:02 Q5. Prove the trigonometric identities, where the angles involved are acute angles for which the expressions are defined
00:04 q5 (i)
00:18 PROCIDURE FOR SOLVING Trigonometric equations
00:30 consider LHS of the trigonometric equations
00:40 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.
01:15 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
02:39 trigonometric equation is proved

03:01 Q5. Prove the trigonometric equations using trigonometric identities, where the angles involved are acute angles for which the expressions are defined
03:04 q5 (4)
03:29 solving trigonometric identities procedure
03:45 consider LHS of the trigonometric equation
03:56 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.
04:43 consider RHS of the trigonometric equation
04:58 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
05:28 a squared minus b square formula
05:55 LHS & RHS of the trigonometric equation are equal.
Hence,trigonometric identity is solved

06:09 Q5. Prove the trigonometric identities, where the angles involved are acute angles for which the expressions are defined
06:38 Procedure for solving Trigonometric equations
06:51 Consider LHS of the trigonometric equation
08:08 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.
cosec A = 1 / sin A.
08:53 Use Pythagorian Identity
08:54 secant squared theta minus tan squared theta = 1
09:28 Simply the trigonometric expression.
09:30 LHS is RHS of the trigonometric equation.Trigonometric equation is proved.
