The curves behind most graphs.
Choose a function, then follow one input as it moves across the graph. Waves repeat, exponentials race away, and logarithms only exist to the right of zero.

Why use a log scale?
Here are four real sizes, from a human hair to Earth’s diameter. They span over 11 powers of ten.
On the linear ruler, all but Earth collapse into the left edge. The log ruler gives every tenfold jump the same width, making the full range usable without changing the underlying sizes.
These are the standard real-valued forms: angles are in radians; tan(x) is omitted at its vertical asymptotes; and ln(x) and log10(x) are undefined for x ≤ 0. The moving dot is a changing input, not a physical object. See the function overview and logarithm definition.
