hello professor, what is the geometrical interpretation of a plane?

[MrFunatabi]

Hi professor,

What is the geometric interpretation of the case where Δ = 0 if we use z = λ? It's on slide 15 around 55:00. Thanks!

Hi MrFunatabi The geometrical interpretation is that the intersection of the two planes that we started with is actually parallel to the xy plane. So it does not meet any plane z=lambda (which is a plane also parallel to the xy plane) in a unique point.

Its very hard to imagine 3d...

anyway Thanks prof..

haha, I love how odd professors can be. Example, drum stick pointer.

Hi theNewCodingFrontier

What's odd about a drum stick? Has a certain practical utility. And of course it rocks and rolls...
