please need some brain power here to help me with this problem. I'm stacked here and I cannot find a solution.
I would like to find the intersection between a plane and a quadric surfaces. Please notice that the two equations are written like f(x,y) and g(x,z) respectively. My first problem is that I cannot visualize the two surfaces correctly as implicitplot3d of the quadric surfaces displays nothing in return.
I want then to find the centre of the ellipse and plot the point and the two surfaces all together in the same 3d plot. Somehow I canont make it. What is wrong with me?
I am pasting here my MWE.
Any kind of help would be really appreciated. Thank you so much.
