Give the integral formulas for the areas of the surfaces of revolution formed when a smooth curve \(C\) is revolved about (a) the \(x\) -axis and (b) the \(y\) -axis.
True or False?, Determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false. The graph of the parametric equations \(x=t^{2}\) and \(y=t^{2}\) is the line \(y=x\).
Consider the parametric equations \(x=4 \cot \theta\) and \(y=4 \sin ^{2} \theta, \quad-\frac{\pi}{2} \leq \theta \leq \frac{\pi}{2}\). (a) Use a graphing utility to graph the curve represented by the parametric equations. (b) Use a graphing utility to find the points of horizontal tangency to the curve. (c) Use the integration capabilities of a graphing utility to approximate the arc length over the interval \(\pi / 4 \leq \theta \leq \pi / 2\)
Sketch a graph of the polar equation. $$ r=2 \theta $$
(a) Each set of parametric equations represents the motion of a particle. Use a graphing utility to graph each set. $$ \begin{aligned} &\begin{array}{ll} \underline{\text { First Particle }} \\ x=3 \cos t \end{array} \quad \frac{\text { Second Particle }}{x=4 \sin t}\\\ &\begin{array}{ll} y=4 \sin t && y=3 \cos t \\ 0 \leq t \leq 2 \pi && 0 \leq t \leq 2 \pi \end{array} \end{aligned} $$
