The standard form for a circle is
\n" ); document.write( "(x-a)^2 + (y-b)^2 = r^2 where
\n" ); document.write( "(a, b) is the center of the circle and r is the radius
\n" ); document.write( "for example
\n" ); document.write( "x^2 + (y-3)^2 = 5 then
\n" ); document.write( "(a, b) is (0, 3) and radius is square root of 5
\n" ); document.write( "
\n" ); document.write( "
