Step-by-step explanation:

Given:

where,

We need to draw the graph of polar curve.

It is flower shape graph.

whose number of leaf would be n

Here, we have polar equation

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: the common difference is -0.10
