### Combine plots with built-in Maxima

I want to combine the following plots as one output figure:

```
maxima('plotdf(4*y/x+x*sqrt(y),[trajectory_at,1,1],[x,0,4],[y,0,10])')
maxima('plot2d(1/4*x^4*(log(x)+2)^2,[x,0,4],[y,0,10])')
```

How can I achieve that? However, if there is any way to output a trajectory by Sage directly, I would be very happy. With pure Sage, I've just achieved this so far:

```
plot_slope_field(4*y/x+x*sqrt(y),(x,0,4),(y,0,10),headaxislength=3,headlength=3)
```
