comment Solve this equation symbolically
Well, I don't think the order of the equation can be reduced by Factor, unless we have a special a.

comment Solve this equation symbolically
Er… So what result do you want? The order of the equation is so high that Solve can only give an symbolic solution in that form, and I don't think it can be changed by other approaches.

comment Solve this equation symbolically
If you just want to solve equations symbolically, why not use Solve ?

comment Variable naming changes everything
It seems that only variables that begin with a c d e will work (something like aaa is also OK)… very strange!

+1 for the first one, which can avoid possible duplication of the name of the variables.

But the first two solutions won't work if the equation is something like a - d == b + c - e.

comment Simple problem with Manipulate and Plot
This is explained in the Possible Issues of the document of Manipulate: Manipulate only "notices" explicit visible parameters. You can check the document for more information: reference.wolfram.com/mathematica/ref/Manipulate.en.html

comment How to draw some 2D curves in a 3D plot?
In fact a more general question behind this is how to make a waterfall plot. I found some discussions here

comment ODE and BVP: NDSolve errors
@Petrus Just as a tool for method of exhaustion… Of course some observations for the plots of the solutions are also needed to narrow the range of exhaustion.

comment ODE and BVP: NDSolve errors
It's not surprising that the original initial condition becomes improper when the domain is changed, I guess the key point for solving your problem is to find a proper initial condition, which requires a lot of patience.
