Re: what is K$


Hi,

sometimes one need a auxilary variable, that has no meaning because it
is used as integration variable or as summation index.  But Mathematica
can't perform the integration or summation.  When Mathematica needs such
a variable it names it <letter>$<number> and this is what you see.

Regards

is an example:
| In[5]:=
| DSolve[Derivative[1][f][x]*
| Derivative[1][g][x] ==
| D[f[x]*g[x], x], f[x], x]
|
|
| Out[5]=
| {{f[x] -> E^Integrate[
| -(Derivative[1][g][
| K$74]/(g[K$74] -
| Derivative[1][g][
| K$74])), {K$74, 1,
| x}]*C[1]}}
