Question

Assertion: If sin² θ − cos² θ = 1 and cot² θ − cosec² θ = 1 are trigonametric identities.

Reason: An equation involving trigonometric ratios of an angle is called a trigonometric identity if it is true for all the values of the angles involved.​

Answer 1

Answer:

assertion and reason both are false.

Answer 2

Answer:

D) A is false but R is true

Step-by-step explanation:-

cosec² θ-cot² θ=1 is the identity , not  cot² θ − cosec² θ = 1 .

Therefore A is false.

There is nothing wrong with reason
