You can put this solution on YOUR website! Please help me with this problem. I need to determine if this equation might be an identity (algebraically):
1+cot^2x=(sec^2x)/(sec^2x-1)
Starting with right side:
(1/cos^2x)/((1/cos^2x)-1)
(1/cos^2x)/((1-cos^2x)/cos^2x)
cos^2x cancel out
1/1-cos^2x
1/sin^2x
(sin^2x+cos^2x)/sin^2x
1+(cos^2x/sin^2x)=1+cot^2x
verified:
right side=left side
so equation is an identity
