These notes are not official in any way, but if you are new to this group you may find them helpful.
1. Messages posted to <sci.math> may be about mathematics at any level. Please don't post OT (off-topic) messages about other things.
Be cautious about cross-posting (posting the same message to more than one news group) - see section 6 below.
Some questions may have better luck in a more specialized news group such as <sci.stat.math>, <sci.logic> or <sci.math.num-analysis>.
2. Your subject heading should show briefly what sort of mathematics is in your message. For example, "Differentiating trig functions" is a good subject, but "Help!" is a bad subject.
3. Include the text of your question in the message itself (not the subject heading), even if you also refer to a web page for a good diagram.
4. Type mathematical formulae in the ordinary ASCII characters on your keyboard.
Use ^ for powers, for example aaaa = a^4 .
You will rarely need * for multiplication, but use plenty of brackets/parentheses. For example, e^2x/5 could mean (e^2)x/5 or (e^(2x))/5 or e^(2x/5).
Use plenty of spaces. For example, 2x + 5y = 12 is easier to read than 2x+5y=12.
5. This news group is open to everybody. Some people have bad manners, and some cranks presume to know more mathematics than they really do. You may be wise to ignore them. Proper news readers (not Google) usually provide filters which can help you to exclude junk messages.
