### latex in plots

I want to display the formula for the graph of a function that sage has plotted without typing the expression manually, because sage has calculated it. For example the n-th Taylor polynomial expansion of a function:

```
f = sin(x)
g = f.taylor(x, 0, 13)
P = plot(f,(x,-10, 10), ymin =-4, ymax = 4, color="blue", axes=True, aspect_ratio=1, thickness=3)
Q = plot(g,(x,-10, 10), ymin =-4, ymax = 4, color="red", axes=True, aspect_ratio=1)
R = text(r"$%s \approx %s$" %(f,g),(0,yzoom[1]+1),rgbcolor=(1,0,0))
show(P + Q + R)
```

Everything works fine except for two things in the displayed formula:

- the * s are shown (which I can live with)
- The two digit exponents are not shown correctly which I assume it is because there are no curly brackets around them in the string g.

**Are there better ways of doing this?**

P.S. Are there ways of writing up the parts of the text in different colors, without defining two pieces of text and trying to figure out their relative positions?
