what does a zero with a line verticly through the middle of it mean?
and what does a more curvatious m mean?

the "zero" could be a theta. its a greek letter and its most commonly used to notate an angle in geometric stuff.

as for the M, i have no idea what you are talking about.

A vertical line is Phi, not theta, which uh.. I can't remember using Phi's for anything yet. Sorry.

Edit: Here's a Phi article I found from a google search. Hope it helps

my experience with notations is they represent whatever the prof/book want it to represent

the "curvatious" M is probably a "mu". it's a greek symbol used to represent the coefficient of friction in physics. it's used in statistics too, but i hated that class so i forgot everything i could about it right away.

a zero with a verticle line through its middle flux from physics?

it could also be a way for bad writers (my self for example) to help distinguish O's and o's from 0'.

if this

is what you are talking about, then yes, it is [url=http://web.ift.uib.no/Fysisk/Teori/KURS/WRK/TeX/symALL.html]phi[/quote]

Why cant people google? (Google "Math Symbols", yeesh...) of course, i had a teacher who used it as theta, and a math teacher that used Alpha for i

so it realy depends on the person.

i believe phi can be drawn with a line that is either vertical or diagonal.

but an "o" with a diagonal line usually means "does not exist".

Stupid math, why cant it just use english!

The zero with the diagonal slash represents the empty set.

Phi is usually used for angles, just like theta. When two different angles are needed in one equation, often theta and phi are both used.
