After using DSolve to a set of differential equations, three constants arise. They are C, C and C. I have checked thoroughly that there are no C, C,....C. It is quite mysterious to me as normally the constants are in numerical order. Is there any relationship between C and C or C? Thank you very much.
According to the documentation for
- The typical default setting is
GeneratedParameters -> C.
- The setting
GeneratedParameters -> fspecifies that successive generated parameters should be named
- In typical cases, the
f[i]are used to parameterize families of solutions to equations.
f[i]usually correspond to free parameters, but are also sometimes used to represent arbitrary functions.
f[i]have indices that start at 1 for each invocation of a particular symbolic operation.
Presumably there were (at least) 21 invocations of "a particular symbolic operation." Without more information about your functions it is hard to be more specific.
