Finding more points for an R^4->R^2 matrix

  1. Oct 21, 2011 #1
    You may assume that all functions in this problem are differentiable at the indicated points
    a) if F(x,y,z,t)=(t^2exp(x+yz),z^2exp(y+xz) compute Df(1,0)

    now we know how to find the matrix, but what we don't know how to do is find additional points for z and t. any help would be great.

    I don't understand your question. The problem says "at the indicated points" and gives (1, 0). What other points do you want? If you have found the matrix form of the derivative, evaluate it at (1, 0).
