Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
 ← expand numerator/denominator using FOIL
 ← expand numerator/denominator using FOIL
=  
 
= 
= 
= 
= cot²A = right side , thus proven
