I'm not seeing this. Indeed,

```
sage: latex(solve (temp,diff(y)))
\left[D[0]\left(y\right)\left(x\right) = \frac{45 \, y\left(x\right)^{\frac{2}{5}}}{2 \, {\left(5 \, \sqrt{x} y\left(x\right)^{\frac{2}{5}} + 6 \, \sqrt{x}\right)}}\right]
```

which shouldn't have this.

Unless you're referring to the `D[0](y)(x)`

with the `(x)`

part? But remember, you defined `y`

to be a function of `x`

. So solving for `diff(y)`

will still solve for it in this sense. You can't (in Sage) ask for the "type" of a symbolic function to change like that. At least, I think that might be what you are referring to?
