## 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 re-arrange [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
