finally i understand 3D ....my god,, the confusion of the whole month struggling to figure out the simplest image you easily paint in my mind AMAZING .we real need the patient prof in our univesities
Yes, you are correct if you only need the graph of the plane. If you are asked to find the traces, which we were in this question, you would need to also graph each trace as shown. Thank you for the comment.
Thanks for the great video! My only question is why would you do all 3 plane intersects when you can sketch the plane by only doing two of those three? were you just trying to show us as an example? Thanks :)
it's just a flat standing plane (no inclination/slope) on y = 3, y = 3 on 2d graph is a flat and have no slope, y = 3 on 3d graph is similar but in 3d it's a plane instead of a line
anyone know how to construct a cross section of cube with 3 points known ? with geometry or maybe how to find all intersection point of plane crossing the cube with linear algebra (still with 3 points known) ?
