I am using Maxima/wxMaxima in Windows to perform a calculation and I get a nicely formatted equation as output in wxMaxima. I can copy the Latex code of the equation and paste it into a math box in Lyx (Insert Math) but it is rendered as the raw Latex code instead of the formatted equation. How can I get the equation from wxMaxima to appear properly in Lyx?

The reason why pasting is different from typing is because when you paste, LyX tries to detect what content you are pasting. It can detect LaTeX, for example, which is what it does in this case and it then runs tex2lyx to import the LaTeX into LyX's format (although for math there is not much conversion that needs to be done I believe). When you type, LyX sees it as character by character, so it does not try to detect the format.
You might be interested in preview boxes. In your TeX Box example, select the red box (the box, not what's inside the box) and then go to Insert > Preview. That will put a black box around the red box. Note that your TeX Code is incomplete as it is. You have to surround it with $ (or similar), just like in LaTeX. After you have the preview box, move click outside so that LyX knows to refresh the box. Then you should see your expression as LaTeX would display it.
Below I show a screen shot with duplicate expressions. That is, both are a TeX box inside of a preview box. The only difference is that in the top one I have my cursor inside it.
I'm not sure why there is no space between "if" and "n". Did you make a mistake in your post or did I make a mistake?
Type 'H', then Insert > Formatting > Subscript, then press the right arrow (this gets you out of the subscript), then type '0'.
You can assign this operation to a key shortcut such as [Ctrl]+[,] using script-insert subscript (see also: lyx shortcut for superscript and subscript).

The equations you copy from Maxima, e.g.
include opening and closing delimiters for a math environment, in this case
\[and\]. In LaTeX, they denote the start and end of a displayed, unnumbered equation. However, when you make an equation in LyX, you already have such delimiters, so you shouldn't add a second set.Hence, if you don't copy the starting
\[and closing\]it works fine.The method mentioned by Scott Kosty in the comments also work fine: After copying the entire equation, including delimiters, do Edit --> Paste special --> Paste from LaTeX, without inserting a math environment first. Then LyX will read the delimiters from the code and insert the proper math environment.
