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.Apply trigonometric identities to Solve Trigonometric Equations.

00:02 CCSS.MATH.CONTENT.HSF.TF.C.8 example q5 (10). Prove the trigonometric identities, where the angles involved are acute angles for which the expressions are defined
00:33 Learn how to prove trigonometric identities through our working model.
00:56 consider LHS of the trigonometric equation
01:05 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.
cot A = 1 / tan A
01:56 consider middle expression of the trigonometric equation
02:10 use Reciprocal Identity
03:35 trigonometric identities are proved.

04:03 q5 (8).
04:32 Procedure for solving Trigonometric equations
04:28 Consider LHS of the trigonometric equation
05:05 algebra maths formulas | Algebraic Expressions and Formulas
USE (a-b)^2 expanding formula
06:02 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.
06:33 Use Pythagorian Identity
06:32 Cosecant squared theta minus cot squared theta = 1
06:40 secant squared theta minus tan squared theta = 1
06:57 Simply the trigonometric expression.
07:17 LHS is RHS of the trigonometric equation.Trigonometric equation is proved.

07:35 CCSS.MATH.CONTENT.HSF.TF.C.8 example q5 (4)
07:58 solving trigonometric identities procedure
08:02 consider LHS of the trigonometric equation
08:27 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.
09:10 consider RHS of the trigonometric equation
09:29 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
09:52 a squared minus b square formula
10:23 LHS & RHS of the trigonometric equation are equal.
Hence,trigonometric identity is solved

10:36 CCSS.MATH.CONTENT.HSF.TF.C.8 example q5 (7)
10:55 Procedure for proving Trigonometric equations using trigonometric identities
11:00 Take LHS of the trigonometric equation
11:51 Quotient Identity
tan A = sin A/cos A.
12:03 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
12:34 solving trigonometric expressions
13:11 LHS is RHS of the trigonometric equation.Trigonometric equation is proved.
Using the fundemental identities and the Pythagorean Identities
multiple examples of verifying trigonometric identities
How to Solve Trigonometric Identities Proving Problems
method to solve trigonometric identities problems
the Quotient Identities, Reciprocal Identities, and the Pythagorian Identities.
