Question

Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:

Assertion (A) : Cot A is the product of Cot and A.

Reason(R): The value of sinq increases as q increases.

• A. Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  
  
• B. Assertion (A) is false but reason (R) is true.
• C. Both assertion (A) and reason (R) are true and reason
• D. Assertion (A) is true but reason (R) is false.

Answer 1

The correct option is B Assertion (A) is false but reason (R) is true.

Cot A is not the product of cot and A. It is the cotangent of ∠A

∴ Assertion is incorrect.

The value of sinq increases as q increases in the interval of < <90

.∴ reason is correct.

Hence assertion is incorrect and reason is correct.
