[math]f:\mathbb{R}\to\mathbb{R}[/math]

[eqn]\exists \hspace{0.2cm} \delta > 0 \hspace{0.2cm} \text{such that} \hspace{0.2cm} \forall \hspace{0.2cm} \epsilon > 0 \hspace{0.2cm} \forall \hspace{0.2cm} x , \hspace{0.2cm} (|x| < \delta \implies |f(x)| < \epsilon) [/eqn]

good god how do I reparameterize the curve
[eqn]\vec{r}(t) = a\cos^{3}(t)\hat{i}+a\sin^{3}(t)\hat{j}+2\cos(2t)\hat{k}, \hspace{0.3cm}0\leq t \leq \frac{\pi}{2} [/eqn]
in terms of the arc length measured at a point where t=0?
