Notes: Type an expression into the box and press Enter. Arithmetic operations include +, -, *, /, as well as ^ for exponentiation, and unary minus.
You can set variables like "x=1.2" and clear them with "x=".
All variables, the input expression box text, and the last 1200 characters of the history box are saved for 14 days in a cookie. You can refresh the cookies by performing some calculations.
Now you can even draw graphs. Try "y=Sin(x)/x".
I would like to acknowledge CRBond for the core parsing code that I'm using (evald) and his implementations of the gamma, loggama, and various Bessel functions.
