The vector equation for the line of intersection is calculated using a point on the line and the cross product of the normal vectors of the two planes. Also, if you wanna tackle this one: At what points does the curve r(t) = (2t^2, 1 − t, 3 + t^2) intersect the plane 3x − 14y + z − 10 = 0? The equation of this plane is independent of the values of z. thus for any values of x and y that satify the equation, any value of z will also work.

The cylinder: x^2 + y^2 = 625 The plane: z = 1 x(t) = cos(t) y(t) = sin(t) z(t) = 1 If you don't get this in 3 tries, you can see a similar example (online) However, try to use this as a last … An ellipsoid is a surface described by an equation of the form Set to see the trace of the ellipsoid in the yz-plane.To see the traces in the y– and xz-planes, set and respectively. The point-normal form consists of a point and a normal vector standing perpendicular to the plane. 12. Find parametric equations of the curve given by the intersection of the surfaces. This algebraic equation states that the vector X P is perpendicular to N. The plane is parameterized by X( ; ) = P+ A+ B (2) where N, A, and B are unit-length vectors that are mutually perpendicular. The analytic determination of the intersection curve of two surfaces is easy only in simple cases; for example: a) the intersection of two planes, b) plane section of a quadric (sphere, cylinder, cone, etc. (a) The plane  y + z = 3  intersects the cylinder  x^2 + y^2 = 5  in an ellipse.

For the general case, literature provides algorithms, in order to calculate points of the intersection curve of two surfaces. (b) As the number c varies, the line L sweeps out a surface S . WLOG the cylinder has equation X² + Y² = 1 (if not, you can make it so by translation, rotation and scaling).. Then the parametric equation of the circle is. When a quadric surface intersects a coordinate plane, the trace is a conic section. The next easiest way to calculate this is to solve using MathCad or similar software.

I rewrite and plot this equation in parametric form to obtain the intersection of the plane with the xy plane. In order for there to be no points of intersection, we would have to have a line which was parallel to the plane, which is very unlikely. The plane can be identified by the vector orthogonal to it.
