Partial Derivatives

  1. May 13, 2009 #1
    1. The problem statement, all variables and given/known data
    x & y measured in meters. Temperature is T(x,y) Temperatures are noted in table
    y= 2 4 6
    x
    4 74 72 68
    6 87 80 75
    8 90 86 80

    Estimate the value of Txy(6,4)

    &

    Tu, where u = (i + j)/[tex]\sqrt{2}[/tex] I do no understand how to get the i and j components


    2. Relevant equations



    3. The attempt at a solution

    Tx(6,4) = (86-80)/(8-6) = 3
    Tx(6,6) = (80-75)/(8-6) = 2.5

    Txy = [Tx(6,4) - Tx(6,6)]/2 = [3 - 2.5]/2 = .25
