I would like MATLAB to draw the plot for the curve described by the following equation, where for instance (a,b,d) = (-10,-10,-10) is a point in 3D cartesian space and c = 2. x and y are the variables. Are there any thoughts?
x^2(1+1/c.^2) -2ax + y^2(1+1/c.^2) – 2by+(a^2+b^2+d^2-r^2)-2d/c(sqrt(x^2+y^2)) = 0
ps. the equation is actually the intersection of a sphere and cone and can be seen in http://mathworld.wolfram.com/Cone-SphereIntersection.html
