Let y(x) be a real valued function defined on the interval by means of the equations:

show that the equation representing an arc that intersects the real axis at the point and

I'm not sure if I'm picking the right values for this, but I would think that it would something along the lines of:

this is the part that I'm not sure of, but continuing would give me:

putting the above equation into Maple gave me:

for some reason this doesn't look correct.
