Let $s(t_1, t_2)$ be the path travelled between $t1$ and $t2$, $T = \sqrt[3]{\frac{11}{4}}$ Then $s(t_1, t_2) = s(t_2) - s(t_1)$ Since the particle is moving in one direction for $t \in [0, T]$ and in the opposite for $t \in [T, 8]$, our answer should be: \[ \abs{s(T, 8) - s(0, T)} = \qty(s(8) - s(T)) - \qty(s(T) - s...

A function F is purely discontinuous if it equals the sum of its jumps, i.e. if F(x) = $\Sigma_{y\leqx} (F(y)-f(y^-))$ for all x
