**Example: Computing the Length of a Curve**

You can use `quad`

or `quadl`

to compute the length of a curve. Consider the curve parameterized by the equations

A three-dimensional plot of this curve is

The arc length formula says the length of the curve is the integral of the norm of the derivatives of the parameterized equations

The function `hcurve`

computes the integrand

Integrate this function with a call to `quad`

The length of this curve is about 17.2.
