    Monotonic Transformation Clarification

    So I understand that a monotonic transformation preserves the order of a function, but I was wondering: could you perform a transformation by multiplying by a variable? For example the formula: U = (XY) - (XY/(Z+1)) Is it an acceptable monotonic transformation to multiply the whole...

    Maximizing a Function with a Constraint: The Lagrangian Approach

    Although, I've been reading that extreme values can occur at endpoints, stationary points, and singular points. So obviously this function has some singular points, but I do not know enough to go any further. Could there be a max at the asymptotes?

    Maximizing a Function with a Constraint: The Lagrangian Approach

    I'm thinking you are probably right. On an exam no less :S. Guess I should have known better. Thanks again.

    Maximizing a Function with a Constraint: The Lagrangian Approach

    Thanks for the reply, you are making sense to me. I'm still confused as to why I was asked to maximize it, when there are no maximum points?

    Maximizing a Function with a Constraint: The Lagrangian Approach

    Homework Statement Seems straightforward enough, Lagrangian optimization Homework Equations Find the max of x^-1 + y^-1 subject to the constraint m=x+y The Attempt at a Solution At first I thought no problems, x*=y*=m/2, however: Using the Lagrangian formula yields...
