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 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

03:00 CBSE solutions for class 10 maths Chapter 8 Trigonometry Exercise 8.4 Q5. Prove the trigonometric equations using trigonometric identities, where the angles involved are acute angles for which the expressions are defined
03:03 CBSE solutions for class 10 maths Chapter 8 Trigonometry Exercise 8.4 q5 (2)
03:19 Procedure for proving Trigonometric equations
03:41 consider LHS of the trigonometric equation
04:20 algebra maths formulas | Algebraic Expressions and Formulas
USE (a-b)^2 expanding formula
04:58 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
05:59 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

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

@strykerstennis

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
