00:02 CBSE solutions for class 10 maths Chapter 8 Trigonometry Exercise 8.4 Q5. Prove the trigonometric identities, where the angles involved are acute angles for which the expressions are defined
00:20 Procedure for proving Trigonometric equations using trigonometric identities
00:25 consider LHS of the trigonometric equation
00:40 Multiply both the numerator and denominator by the conjugate of the denominator.
01:10 use algebra maths formulas | Algebraic Expressions and Formulas
use (a-b)^2 expanding formula | a squared minus b square formula
01:50 Use Pythagorian Identity
sin squared theta plus cos squared theta = 1
00:24 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.
02:41 LHS = RHS. 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.

@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
