**Problem 6: Finding the Arc Length of Paths**

Use a calculator to compute the integrals in parts (b) and (c) as there are no antiderivatives for these.

**a)** Calculate the arc length of the portion of the helix given by the vector function \(\vec{c}(t) = (2 \cos t, 2 \sin t, t)\) for \(0 \leq t \leq 2\pi\).

**b)** Determine the arc length for the path described by \(\vec{d}(t) = (t, t^2/2, t^3/3)\) over the interval \(0 \leq t \leq 1\).

**c)** Find the arc length of the graph described by the equation \(x = y^3 - 2y^2 + 1\) within the bounds \(-2 \leq y \leq 3\). Begin by parameterizing the curve.
