Mathematics
x = (cosec A + cot A)(1 - cos A) Assertion (A): x = sin A Reason (R): x = (1⁄sin A + cos A/sin A)(1 − cos A)= (1 + cos A)(1 − cos A)/sin A= sin²A/sin A = sin A. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true and R is correct reason for A. 4. Both A and R are true and R is incorrect reason for A.
