 Taking LHS,we have 
=cot²A(secA-1)/1+sinA 
=cot²A(secA-1)(1-sinA)/((1+sinA)(1-sinA... 
=cot²A(secA-1)(1-sinA)/(cos²A) 
=(secA-1)(1-sinA)/(sin²A) 
=(secA-1)(secA+1)(1-sinA)/(sin²A)(secA+... 
=(sec²A-1)(1-sinA)/(sin²A)(secA+1) 
=(tan²A)(1-sinA)/(sin²A)(secA+1) 
=((sin²A)/(cos²A)(1-sinA))/(sin²A)(secA... 
=(1-sinA)/((secA+1)(cos²A)) 
=sec²A(1-sinA)/(1+secA)=RHS 


I HOPE YOUR PROBLEM IS SOLVED!!!!!
