Section 9.6 : Polar Coordinates
9. Sketch the graph of the following polar equation.
\[\cos \theta = \frac{6}{r}\] Show SolutionMultiplying both sides by \(r\) gives,
\[r\cos \theta = 6\]and we know from the notes on this section that this is simply the vertical line \(x = 6\). So here is the graph of this function.
