Homework Statement
Y=[itex]\frac{\sqrt{1-x^2}}{(2x+1)}[/itex]
Homework Equations
I took the first derivative which I believe to be:
[itex]\frac{(-x-2)}{(2x+1)^2\sqrt{1-x^2}}[/itex]
I also took the third which I believe to be:
[itex]\frac{4x^3+12^2-7}{(2x+1)^3(1-x^2)^(3/2)}[/itex]
I am trying to find zeros of the derivatives and they are all seemingly outside the domain of the original. I don't know what to do in a case like this. There appears to be no real solutions for the second derivative. What does this all mean?
