Question

Draw a graph of the rose curve. r = 4 cos 2θ, 0 ≤ θ ≤ 2π

Answer 1

Answer:

Attachment

Step-by-step 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
