Thank you so much for your videos from 14.1. You walked me through these chapters with very straightforward problem solving and knowledge explanation when my Professor's lectures are just him reading again what is in the textbook. I am looking forward to seeing more of your videos.

Hey Alexandra! I miss your videos so much :(( I'm currently doing a multivariable unit and you've got me through it thus far. I really wish you had uploaded more lectures covering this unit. You have my utmost gratitude :D

First of all, I love your videos. I LOVE THAT YOU EXPLAIN THE ORIGIN AND HOW EVERYTHING GOES FROM CALC 2 TO CALC 3. Can you please post notes for 14.7 part 2.

at 37:11 why is Fxx < 0 in the table if for the critical point (-1, -1) you would sub that into Fxx which is -12(-1) = 12 > 0 hence should it not conclude to be a relative/local minimum?

how is 128 <0 in the table as it is a positive value and is greater than 0?

Hi, I am currently a college student with no money, but if you have a venmo, I would gladly give you what I have left because your videos saved my GPA and actually taught me math. Thank you, from the depths of my soul.
