Hi! I try to help You. 1. What is it $:=kg^0.8*m^2.6/s^1.6 We can use $:=cd for inserting in sheet currency (see my messages in Economic & Finance miniforum). 2. I think COST(H, T.max):=((H/m)^1.8*(T.max/N)^0.8)*$ 3. Guess value must be just higher Given key-word. Good Luck! Valery Ochkov http://twt.mpei.ac.ru/ochkov
1. $:=kg^0.8*m^2.6/s^1.6 is a definition I used to get the answer in $. 2. Your method to convert the answer to $ is much better. 3. Can mathcad minimize a system of equations, or can it only minimize a single equation and its variables?
I have a series of equations which give me the values of H and T.max. Mathcad only seems to optimise the single equation, ie COST(H, T.max):=((H/m)^1.8*(T.max/N)^0.8)*$ I need it to optimise a system of equations to give the minimum value of COST.
Hi! I see you problem but sorry - no time to correct your sheets. I will take your task my student. Solvers in Mathcad and in Excel was made one firm Frontline Systems, Inc. Difference: In Excel we can use integer solutions In Mathcad we can use units See now for help:
Probably not of great interest to the original poster any more, but still a good example. It's quite simple once you keep track of what is a function of what. In XL cells are implicit functions of other values, as referenced. In Mathcad values are just values, and functions must be explicit.
