Several questions throughout class.

numpy

Example: approximately exponential separation of trajectories in mayfly model

How to define and calculate the "best" straight line? Last time, several measures of badness were suggested.

Exploration: Let's compare how they work.

Pointwise error *e*_{i} = *α**x*_{i} + *β* − *y*_{i}

Analytical solution for choice *E* = ∑^{n}_{i = 1}*e*^{2}_{i}

argmin_{(α, β) ∈ ℝ2}
