Help: Mathematical Formulas

Formulas can be entered in normal mathematical format. The usual algebraic precedence rules are observed. Multiplication can be indicated with either a blank space or "*". Powers are indicated with "^". Factorials are indicated with "!". The constant pi and the following mathematical functions are available:

abs	arccos	arcsin	arctan	arg
binom	ceil	cos	cosh	exp
floor	gamma	if	ln	max
min	product	round	sgn	sin
sinh	sqrt	square	sum	tan
tanh

Points to remember:

the arguments of a function must always be enclosed in parentheses, e.g. "sin(x)", not "sin x".
"x*y" can be written as "x y" but not "xy"
"a^b" is defined in the following cases:
- a > 0 and any b (unless the number becomes too large)
- a = 0 and b >= 0 (with the convention 0^0 = 1)
- a < 0 and b an integer (unless the number becomes too large)

If you make a syntax error in your equation, the equation turns red. The error message can be seen in Netscape's Java Console. Correct the error and press Enter, and the equation should turn black again.
