This paper deals with an extension of a classical Calculus problem: Two ladders are extended across two walls and joined at the top, and the sum of the lengths of the ladders is to be minimized. We derive a minimization problem for a function of two variables for this task and we inspect special cases. The software package Maple will be used in examples.
