What is mean to put cap sign in formula why we are using the cap sign in the circle equation as it came from distance formula...why sir?

Hi Raj,
The equation of the circle is
(x - h)^2 (y - k)^2 = r^2
Since it is (x - h), we have to put a minus sign after h.
So, we write (x - 5) = (x - (-5)),
As -(-5) = 5
And we get value of h = -5
