MOD NOTE: This was originally an off-topic set of posts in the following thread:

As such, there is some content here that applies to the context of that thread and might be confusing without that context.
[tex]\cos\left ( \phi \right ) [/tex]
\(\cos\left ( \phi \right ) \)
The problem is that when you just have text ("cos" in this case) in a Latex equation weird things can happen. But most of the common functions it can deal with as "\cos".
Another option is to mark the "cos" in a "\text" tag.
[tex]\text{cos}\left ( \phi \right ) [/tex]
\(\text{cos}\left ( \phi \right ) \)
Personally, and this is pure personal preference, I like leaving a space prior to escape characters and also munching the parens together:
[tex] \cos \left( \phi \right) [/tex]
Also, in most cases you can actually leave the 'left' and 'right' out. I think I have encountered situations in which they are needed, but I actually haven't been able to come up with one recently.
[tex] \cos \( \phi \) [/tex]
\( \cos \( \phi \) \)

Try:Let
\(cos\left ( \phi \right )=\frac{1}{2}G\left ( -H \right )^{-\frac{3}{2}}\)
[tex]\cos\left ( \phi \right ) [/tex]
\(\cos\left ( \phi \right ) \)
