Section 9.6 : Polar Coordinates

11. Sketch the graph of the following polar equation.

\[r = - 14\cos \theta \] Show Solution

We can rewrite this as,

\[r = 2\left( { - 7} \right)\cos \theta \]

and so we know from the notes on this section that this is simply the circle with radius 7 and center \(\left( { - 7,0} \right)\).

So here is the graph of this function.
