In Exercises \(71-90,\) convert the rectangular equation to polar form. Assume \(a > 0\). $$2 x y=1$$
The equation \(r=\frac{e p}{1 \pm e \sin \theta}\) is the equation of an ellipse with \(e<1 .\) What happens to the lengths of both the major axis and the minor axis when the value of \(e\) remains fixed and the value of \(p\) changes? Use an example to explain your reasoning.
Find the distance between the point and the line. Point \((-1,2)\) Line \(5 x+3 y=-4\)
The graph of the parametric equations \(x=t\) and \(y=t^{2}\) is shown below. Determine whether the graph would change for each set of parametric equations. If so, how would it change? (GRAPH CANNOT COPY) (a) \(x=-t, y=t^{2}\) (b) \(x=t+1, y=t^{2}\) (c) \(x=t, y=t^{2}+1\)
