List of allowed functions and characters

• All numbers (including the decimal point, when used appropriately)

• T (the parameter variable)

• Parenthesis (make sure they match!)

• +, -, *, /, ^, %

• cos(x), sin(x), tan(x), cot(x), sec(x), csc(x)

• arcsin(x), arccos(x), arctan(x)

• sqrt(x)

• log(x), ln(x), logbase(base,x)

• PI, E

• max(a,b), min(a,b), floor(x), ceil(x), round(x)

Use parentheses after each function, and always use * for multiplication. For example, sin(x), sqrt(x), and ln(x). Logbase x of y is logbase(x,y).

Sample valid entries:

• sin(3*T)

• sqrt(logbase(2, T))

• 3*(E+2)*T

• arctan(PI*((T-17)^2))
