Homework Help: MATLAB Modelling Question

  1. Mar 16, 2016 #1
    1. The problem statement, all variables and given/known data
    Modelling the following equation:

    k = Delta Q / t

    2. Relevant equations

    Q = T2 - T1 = -40 (fixed)

    t = Delta Q / k. I need to find t.

    k can be floating so I suppose 0 to 10 minutes with 0.5 increments

    3. The attempt at a solution

    I don't have MATLAB on me at the moment, but I think I should just set a loop for k, nest the expression for t and the plot a k vs t curve.

    Does that sound right?

    Is the delta Q a fixed constant or does it depend on k or t?

    Delta Q is a fixed variable and rather k, t depend on it as they are floating variables.

    MATLAB is a bit different from python in that its arrays aren't indexable. Say x = [1,2,3,4,5], I can't use x[0] = 1, x[3] = 4, etc.
