Express maximum as an equation

  1. Nov 14, 2007 #1
    Given variables A and B
    How is the maximum of A and B expressed as an equation?
    Another way of saying it is how do you express MAXIMUM(A,B) as an equation?

    Given variables A,B,C
    How do you solve for A?

    For part 1, you can write a piecewise function but it is just typing out what maximum means.

    For the second part, you can't necessarily recover A from C. Suppose that B>A. Then A could be any value less than C.

    How do you write it piecewise again?

    For writing as an equation, I came up with this but it only works when the numbers aren't equal
