Evaluate s(t) = ||r' (u)|| du for the Bernoulli spiral r(t) = (e' cos(5t), e' sin(5t)). It is convenient to take-oo as the lower limit since s(-∞o) = 0. Then use s to obtain an arc length parametrization r₁(s) of r(t). r₁(s) = (x(s), y(s)) (Use symbolic notation and fractions where needed.) r₁(s) =

Question
**Title: Arc Length Parametrization of the Bernoulli Spiral** Evaluate \( s(t) = \int_{-\infty}^{t} \| \mathbf{r}'(u) \| \, du \) for the Bernoulli spiral \( \mathbf{r}(t) = \langle e^t \cos(5t), \, e^t \sin(5t) \rangle \). It is convenient to take \(-\infty\) as the lower limit since \(s(-\infty) = 0\). Then use \(s\) to obtain an arc length parametrization \( \mathbf{r}_1(s) \) of \( \mathbf{r}(t) \). \[ \mathbf{r}_1(s) = \langle x(s), y(s) \rangle \] (Use symbolic notation and fractions where needed.) \[ \mathbf{r}_1(s) = \boxed{} \]
