Yes, that's normal: the backslash character in a string is interpreted as an escape character for special commands; for instance `\f`

stands for an ASCII formfeed. To avoid this and restore the standard LaTeX interpretation one has to type a double backslash, as you did. An alternative is to prefix the string with `r`

(for "raw" string):

```
show(LatexExpr(r"\frac{x}{\cos(x)}"))
```
