Explanation:

Given:
`r=4\cos2\theta`

where,
`0\leq \theta \leq 2\pi`

We need to draw the graph of polar curve.

`r=a\cos n\theta`

It is flower shape graph.

whose number of leaf would be n

Here, we have polar equation

`r=4\cos2\theta`

Coefficient of Ф is 2

Number of leaf should be 4. We will draw the graph using graphing calculator.

Please see the attachment for graph.

Answer 2
