Optimization problems

  1. Oct 28, 2008 #1
    1. The problem statement, all variables and given/known data
    look at jpg attachment


    2. Relevant equations

    T(y)=(z-y/r)+(sqrt(x^2+y^2)/s)
    ac=z
    bc=x
    dc=y
    ab=w
    im having trouble taking the derivative of T(y) and how to solve it

    on the second one i think there is no maximal area but there is a minimal but not sure how to start it
