Calculus 3 Final Review (Part 1) || Lagrange Multipliers, Partial Derivatives, Gradients, Max & Mins

In this video we will be doing 10 in depth questions regarding material that will most likely appear on your calculus 3 final. Timestamps which I forgot to include: Problem 01 -- 00:02:10 -- Finding the Equation of a Plane Problem 02 -- 00:11:05 -- Graphing a Quadric Surface Problem 03 -- 00:18:36 -- Graphing and Finding the Domain of a Vector Function Problem 04 -- 00:22:18 -- Finding Unit Tangent and Normal Vectors + Curvature & Arc Length Problem 05 -- 00:34:00 -- Finding All Second Partial Derivatives Problem 06 -- 00:42:17 -- Finding the Differential of a Three Variable Function Problem 07 -- 00:46:11 -- Deriving the Second Derivative w/ Chain Rule Problem 08 -- 00:53:51 -- Finding the Gradient Problem 09 -- 01:01:45 -- Finding Local Extrema and Saddle Points Problem 10 -- 01:15:00 -- Lagrange Multipliers with 2 constraints Donations really help me get by.

That is why in this video I will be heavily talking about what these certain things, like gradient, directional derivatives, lagrange multipliers, partial derivatives, are actually doing for you. Part 2 will be out before the end of the semester! I hope this video helped! If it did SUBSCRIBE for more content. Thanks for watching!
