`f(x)=e^x`

1 unit to the left, you’re left with `g(x)=e^(x+1)`

(Fig. A). This transformation is pretty simple; the new line is 1 unit away. However, it’s only 1 unit away horizontally. Vertically, it varies depending on the x value. The vertical difference at x=-1 is a lot smaller than the vertical difference at x=1.
On this recent #hack-night, @carrot and I set out to transform `f(x)`

so that at any point along `f(x)`

, the distance to the closest point on `g(x)`

is equal to 1. Essentially, `g(x)`

is 1 unit away throughout, not horizontally (Fig. B).
This proved to be quite difficult. There were a lot of quadratics that needed solving, and we also had to use the pythagorean theorem to get some distances. He can probably explain the math behind it a lot better than I can.
