Beyond simple math and grouping (like "(x+2)(x-4)"), there are some
functions you can use as well. Look below to see them all. They are mostly
standard functions written as you might expect. You can also use "pi" and "e"
as their respective constants.
Please note: You should not use fractional exponents. For
example, don't type "x^(1/3)" to compute the cube root of x.
Instead, use "root(x,3)".
When you want a quick graph of a function, you can just go to

You can even separate multiple equations with commas, like
