![]() ![]() For example something like this for the $v-x$ plot:Ĭan anyone point me in the right direction so I can find the values for the equations? any help would be appreciated. I could replicate the $l=3$ one but for the rest, especially $l=6$ and greater I'm having problems finding the right values, because I'm getting solutions that are not correct. I'm trying to get some results similar to these: Also we have symmetry along the $x$-axis at midpoint and the derivates of $r$ and $v$ with respect to $x$ are both zero $r'=v'=0$ but for lengths greater than 3, I keep getting solutions that doesn't respect the symmetry and doesn't have those derivatives zero at midpoint. Where $r_]īut for length intervals greater $l$ than 3, for example 6, I'm having problem finding the right value for guessing. These Differential Equation Solving with DSolve tutorials will be useful in acquiring a basic knowledge of DSolve and also serve as a ready reference for information on more advanced topics.I'm trying to solve these two coupled 2nd order differential equations: This is provided in the tutorials on ODEs, PDEs, DAEs, and boundary value problems (BVPs).
