Answer:

( cot A cos A )^2 = (cot A + cos A) (cot A - cos A)

Step-by-step explanation:

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

cross multiply,

(cot A cos A )(cot A cos A)=(cot A -cos A)( cot A+cos A)

the RHS is in the format (a + b )(a + b)

that is,

(a + b)^2

(a + b)^2= (a+b) (a-b)

that is,

(cot A + cos A ) ( cot A - cos A)

please mark as brainliest☺️☺️
