Arithmetic 
2*x+1/3 
Standard precedence applies  this gives you "two times x plus one third" 
Multiplication 
2x+(x+1)(x+2) 
Most multiplication can be done without the '*'. 
Exponents 
x^2  This is "x squared" 
x^.5  This is a square root 
2x^2  This is the same as 2*(x^2)

Constants 
e^x  Euler's constant 
sin(2 pi x)  pi 
Absolute Value 
x 
Use the pipe character to make absolute value bars. (press ShiftBackslash) 
Functions 
sin(x)^2 + cos(x)^2 
Functions must have parentheses around their arguments 
ln(x) 
Natural logarithm. Use log(x) for logarithm base 10 
sin(x) 
Trigonometry: also try any of cos, tan, sec, csc, cot, asin, acos, atan, acsc, asec, acot

sinh(x) 
Hyperbolic Trig: also try any of cosh, tanh, sech, csch, coth, asinh, acosh, atanh, acsch, asech, acoth
