the visualisation has an error, it should be

C = @(x) real(-sqrt(R^2-(x-T(1)).^2) + T(2)); % Lower half circle

Thanks Gunther. The function does produce the correct graphic, but only when T(1)=0 as in my example.

Is there any special in Test 3?

Austin Senerchia on 5 Apr 2022

x(1) = -b/(2a)
x(2) = (aR^2) - (3/4)*a - (1/4)(b^2/a) + c

why is this not right? it's close

don't know why the assertions fail.
The solution is correct.

Matt Fig on 9 Feb 2012

If you look at the example posted in the problem description, you will see that the return argument should be a two element row vector.
