Answer 1

Answer:

Step-by-step explanation:

LHS = cos A / (1 - tan A) + sin A /(1 - cot A)

= cos2 A / (cos A - sin A) + sin2 A / (sin A - cos A)

= cos2 A / (cos A - sin A) - sin2 A / (cos A - sin A)

= (cos2 A - sin2 A) / (cos A - sin A)

= (cos A + sin A) (cos A - sin A) / (cos A - sin A)

= (cos A + sin A).
