Mathematics - Multivariable Calculus - Lecture 12

[hotguy2985]

this is an extremely shitty lecture.

the directional derivative is simply given by:

Duf = (x,y)

If we take the derivative of that function that that particular point, it yields the following funciton

dx/dy = dz + 1zy, which is the gradient derivative for the x,y,z, plane

this can be seen in sql

if exists( select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o_id = object _id ('N gradient vector)

Unless you use this information in your profession, it is irrelevant to everyday life.

@JeffersonDinedAlone If you have a car with an engine or a house full of electronic goods, then it is relavent to everyday life.

These videos are for people who want to be educated to work in engineering or science - they're not for general entertainment.

Anyone knows the number of lecture where matrices are explained?

[friedjelly10]

excellent professor

[RsWeChanged]

I have no clue what is being said here but i am somehow interested...

[makier01]

very usefull explanation in for example optimalization...

[bigtimettt]

He's good and all but he takes too much time to get to the actual facts :/

[MINDERAZA]

@bigtimettt Maybe it takes more time, because he want to explain it in more simply way...

Second half of lecture: determining maximum and minimum values for f(x, y).
