Starting from the point $\left( -3, 1, -3 \right)$ reparametrize the curve $$\mathbf{r} \left( t \right) = \left( -3 + 2 t \right) \mathbf{i} + \left( 1 + 3 t \right) \mathbf{j} + \left( -3 + 0 t \right) \mathbf{k}$$ in terms of arclength.

$\mathbf{r} \left( t \left( s \right) \right) =$ $\mathbf{i} +$ $\mathbf{j} +$ $\mathbf{k}$
