Seriously. It’s about time we started talking math on an ongoing basis. This seems as good a place as any to open the floor.

`r ^ 2 = (x - h) ^ 2 + (y - k) ^ 2`

where `(h,k)`

is the centre point of your circle and `r`

it’s radius.

`g = c`

where `g`

is the graph and `c`

is a circle

What will the curve tendency be in this…

```
>>> two_day_change = [23, 39, 56, 74]
>>> x = two_day_change
>>> [b / a for (a, b) in zip(x[:-1], x[1:])]
[1.6956521739130435, 1.435897435897436, 1.3214285714285714]
