This page lets you graph a function of one variable, x. Your function can use the
mathematical constants pi and e; it can use operators +, -, *, /, and ^ where ^ represents
raising to a power; it can use the functions sqrt, cubert, sin, cos, tan, arctan, arcsin, ln,
log2, log10, abs, round, trunc, floor, and ceiling. A function's argument must be enclosed
in parentheses. (The C-style ternary operator ?: is also supported, using boolean operators
==, !=, <, >, <=, >=, not, or, and.) The grapher attempts to draw vertical asymptotes and jump
discontinuities correctly, but it doesn't always work. "Equalize axes" sets the scales on the
x- and y-axes to be the same; the specified limits will be adjusted to enforce this.
