Question 959148
Please Help me answer this question 
Prove the following equation is an identity
sinx/sinx+1 = cscx-1/cot^2x
***
start with right side:
{{{(cscx-1)/cot^2(x)=((1/sinx)-1)/(cos^2(x)/sin^2(x))
=((1-sinx)/sinx)/(cos^2(x)/sin^2(x))
=((1-sinx)/sinx)*(sin^2(x)/cos^2(x))=(1-sinx)*sin(x)/(1-sin^2(x))
=(1-sinx)*sin(x)/(1-sinx)(1+sinx)=sinx/(1+sinx)}}}
verified: right side=left side
