Which is the polar form of the parametric equations x=4 cos theta and y=4 sin theta?

To solve this problem you must apply the proccedure shown below:

1. You have the following parametric equations given in the problem above:

x=4cosθ

y=4sinθ

2. Therefore, you have:

x=rcos θ

y=rsin θ

x=4cos θ

rcosθ=4cos θ

3. Solve for r:

r=4cos θ/cos θ

r=4

Therefore, the answer is: r=4 and assuming that θ goes from 0 to 2 π.
