    multivariable tree diagrams

    The question asks to make a tree diagram and then use the chain rule to compute the derivative at the given point

    1. w=qrs^5, q=t^2, r=t^3+3, s=t-1. Find the derivative of dw/dt(-2)

    2. h(r, s, t)=r^2-t^2+rs, f(x)=(x+1, sqrt.(x^2+9)). Find the derivative Dfoh (2, 0, -3)

    The "root" is the original function, w, from w you have branches to q, r, and s. From each of those, branches to t.
