Question

Finding the area of polar coordinates: One petal of r = cos 5 theta.

I know how to compute the area, I just need to check if I've got the correct limits. I got pi/2 and zero.

Answer 1

We need the limits to provide r=0 or cos(5x) =0 so:

5x = pi/2 --> x = pi/10

5x = 3pi/2 --> x = 3pi/10

So the limits should be pi/10 to 3pi/10. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
