Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.After some thinking, I don't think this is possible. For an arbitrary stage i, the expression for the mass ratio will be this $$N_i =... -
Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.s will be around 0.1. These results make sense but this is a solved issue currently. This is the issue I am currently having

Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.This is nice, but @pasmith pointed out a way to make the Jacobian upper triangular, which makes the computation of ##\Delta X_n## much...

Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.So not related to this specific topic but related to this project. So turns out the equations I was working with are likely wrong. So...

Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.Do you mean it's possible to solve the linear system without using Excel's matrix operations each time? If that is correct, I believe...

Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.There's 3 equations in my post, but that's the version for 2 stages. I want to be able to expand it up to 5 stages where the system of...

Ax_xiom replied to the thread Undergrad Best way to numerically solve this system of equations?.A few problems: I want to implement up to 5 stages, which would result in 6 equations and 6 variables that would need to be graphed...

Ax_xiom posted the thread Undergrad Best way to numerically solve this system of equations? in Calculus.So I'm working on a project where I am trying to work out what the ideal sizes of rocket stages are and I am using Excel to allow the...
