How would you find the bounds for this polar integral
Use a double integral to find the area of the region enclosed by the curve r=4+3cos(theta)

Question

anonymous · Answer

$$r=4+3\cos \theta$$

anonymous · Answer

$$\int\limits_{0}^{\pi}\int\limits_{0}^{4+3\cos \theta}$$

anonymous · Answer

how did you get 0 to pie for the interval of theta

anonymous · Answer

You didn't give me anymore info, I don't know if there is more. Changing r to rectangular I it is a half circle, 0 to pi.

anonymous · Answer

that is the question given in the book, there is nomore information

anonymous · Answer

you don't need more. If you graph it you'll know. It's a cardiod, so the limits are 0 to 2pi, if I remember correctly

anonymous · Answer

and the thing you would be integrating is r dr dtheta
don't forget the r!

anonymous · Answer

would the integration for r still be from 0 to 4+3costheta

anonymous · Answer

That one is set, I just wasn't sure of the angle.

anonymous · Answer

yeah, i agree

anonymous · Answer

chaguanas, so i like posted my question 3 times and that guy you were talking about still hasn't shown up yet
