This video gently introduces the concept of a partial derivative. The idea is naturally motivated through examples. The definition, geometric interpretation and computation of partial derivatives are discussed.

Such an example is usually seen in 1st and 2nd year univsrsity mathematics courses.

  • he speech is superb

  • This is a great help for me.

  • very well done, nice and easy going keep it up sir!

  • this was great, thanks !

  • If i take business course I won't have to learn these things right?

  • Hi,

    Can the videos be freely downloaded? I could not see any link to do that.

  • @FIFAMAN07C3 cause sinx is to be treated as constant when differentiating w.r.t to y.

  • Hello Dr.Tisdell, thank you for your videos. I would like you to help me to solve the following partial differential equation:

    a*dy/dx - b*dy/dt = K(y-yi)

    being a, b and K constants

    this equation translate the mass transfer in a column.

    any help?

    thanks a million.

  • @FIFAMAN07C3 nevermind i just realized that if x is a constant and you take its sine value its also a constant. and that derivative = 0
