Dsolve gives extra term
2 views (last 30 days)
Hello, Im calculating following third term function. I got the following answer without Matlab . However when solving the function with dsolve Matlab gives me this answer .
So my question is, where is this -1/2187 coming from? Is it possible to get rid of it somehow when using dsolve?

Why do you care?
Note that C1 is completely arbirtrary! C1 is an unknown constant!
So you can trivially add or subtract any constant from the result, and the solution is still as valid.
Once you apply initial conditions, then the constant will be absorbed. It will magically go away.
