Homework Statement
I need to optimise a couple of equations.
I want maximum S for minimum x.
Constants:
h, t
Variables:
w, j
Homework Equations
S = ( (j) / (j + 0.5*w) )^2 [Eqn 1]
x = (const) * (j / w) [Eqn 2]
[See attachment]
The Attempt at a Solution
Well...
I've tried to rearrange [Eqn 1] to make j the subject but I cannot. I get:
((j)^2) * ( 1  S + ((S*w)/j) ) = (S*(w^2))/4
I thought that if I rearrange both equations for j or w and set them equal to each other then I can try to find the min/max of the equation (for the other variable).
Any ideas/help please?
thanks
