The Wolfram Language's differential equation solving functions can be applied to many different classes of differential equations, automatically selecting the appropriate algorithms without needing preprocessing by the user. Use DSolve to solve the differential equation for with independent variable :. The solution given by DSolve is a list of lists of rules. The outermost list encompasses all the solutions available, and each smaller list is a particular solution. If you want to use a solution as a function, first assign the rule to something, in this case, solution :. Now, use Part to take the first part of the solution using the short form solution [ [ 1 ] ]. Now, f [ x ] evaluates like any normal function:. To specify initial conditions, enclose the equation and the initial conditions and in a list:. If not enough initial conditions are given, constants C [ n ] are returned:. To indicate which functions should be solved for, use a second list:. First, solve the differential equation using DSolve and set the result to solution :.

I am new to Mathematica and I am trying to model an asymmetric momentum exchange tether in its orbit about the Earth. The tether initially starts as a symmetrical system and simply has the ability to alter the tether lengths to change the CoM and thus account for mass discrepancies causing the system to act asymmetrically. The problem I am receiving is that I am passing three equations to NDsolve. NDsolve accepts the equations as differential equations, and despite providing both boundary and initial conditions to the solver NDsolve is not resulting in a valid list of rules or a dispatch table and thus cannot be used for further evaluation of parameters to plot. I have attached a copy of my most "up to date" model, please forgive me if it is something blaringly obvious, I have been staring at my screen for a considerable amount of time now. The second equation is not a differential equation. The third one is. Apologies, I realise this notebook I uploaded pre-loaded the numerical values into the equations. This is how the Lagrange Equations of motion look once they have been differentiated. R[t] is the radial position of the tether in its orbit about the earth - this is confined to a circular orbit so in -fact yes it would be constant.
