302: Exam 3 or Ch 13 Review - Shared screen with speaker view
This one may of kind of specific but can you do one where we find a point in a plane that is closest to some other point outside of the plane?
where did fxy come from
so right now we just have the critical point, right? We don't actually know if it's a min or max yet right?
Yes this is helpful
What would you do if you were trying to get close to a different point?
I was wondering why z is multiplied to y^2
Could we also do like a maximization story problem?
I think it is positive x
Don't we need to test to find out if it's actually a minimum though?
Wouldn't the gradient also be zero at a maximum though?
These x,y,z values don't add up to one
Yeah that helps
oh cause in 3d there’s 8 spaces
Hey guys! My prof emailed this link out for an exam review, is that what's going on, or are these regular office hours?
Okay, gotcha. Thanks!
I believe that 1 in the answer because +-1 ,0 and 0<+-1 are critical points
And if you plug it into f it is bigger than 2/3 so it is the max
How do you get 0 and 1 as critical points??
from x^2 =y^2
Because x an and y can be both 1 and 0
Ahhh ok thanks
