Minimum Value ProblemDate: 14 Jul 1995 19:38:23 -0400 From: Paul Twynam Subject: Minimum Value Problem Hello! Can you help me with a math problem? I need to find the minimum value of E for E = be^(-ar) - dr^(-6) where b, a, d are constants and r is the variable. The problem is solving the equation E'=0. Can it be done algebraically or is a numerical method required? I would appreciate your assistance.

Even our computer (which runs Mathematica) says "The equations appear to involve transcendental functions in an essentially non-algebraic way." So I think your best bet is to do it numerically for the specific a, b, and d. Sorry we couldn't be more help. -K |
