Multivariable Calculus: Distance from a point to a plane

[@punditgi]

Excellent video! 😊

[@bevinmaultsby]

Thank you! 😃

Honestly, it took me a couple of minutes to see that one does not need to find the point where “l” and the plane intersect. Thanks for the insight.

[@bevinmaultsby]

You’re welcome! You can also find that point if you’d like, there are often multiple ways to proceed.

Hi, if we have more teachers like you, math would be accepted easier. My university math professor tells us "memory this and that", i cant im sorry. hahah

[@bevinmaultsby]

Happy to help!

My approach was we have point (1,2,3) and we have normal vector (3,-1,5) so i did this line (x,y,z)=(1,2,3)+k(3,-1,5) intersected with the plane then calculated the distance between points.

[@bevinmaultsby]

Perfect! That would land right on that point I sketched at the beginning.

[@mmd8075]

@@bevinmaultsby but your approach shows us there are many more approaches and something we forget is we can find many points in a plane and a line.

Hey there. For some reason, I can no longer find your Cal 4 series of videos. Am I overlooking something, or are they no longer available? Thank you!

[@bevinmaultsby]

Gosh, I hope not! I think all my playlists are still here: www.youtube.com/@bevinmaultsby/playlists I don't have anything called Calc 4, you might be looking for Calc 3? kzbin.info/aero/PLBEl4BT8wUgOqJCBijQxClMIuumgtMinc&feature=shared

Sorry for bothering you, then. I thought I remembered seeing it before I left Africa. Probably just wishful thinking.

[@bevinmaultsby]

No worries!
