You have not said anything about x in your problem statement so how do I know if dy/dx includes h?
This is the problem that I got. I thought of that too. I think that it might just be a type? x is probably suppose to be h...
well, y^2 + x^2 = 1 is a circle of radius 1
x = +/- (1-y^2)^.5
y = +/- (1-x^2)^.5
dy/dx = +/- .5 (1-x^2)^-.5 (-2x)
dy/dx = +/- x (1-x^2)^-.5
but we know x = +/- sqrt(1-y^2)
dy/dx = +/- sqrt(1-y^2)/y^2
