							Dont worry you were not able to solve this because it is wrong question .I can show you how it is wrong;[1+cosec(a)]÷cosec(a)=[1+1/sin(a)]÷[1/sin(a)]=[{sin(a)+1}÷sin(a)]÷[1/sin(a)]=sin(a)+1=[sin(a)+1]×[1-sin(a)]/[1-sin(a)]=[1-sin^2(a)]÷[1-sin(a)]=cos^2(a)/1-sin(a);which is not equal to sin^2(a)/1-sin(a).Hope it helps if yes please give approval
