Can someone help me with doing this polar curve? Pleasee

Question

anonymous · Answer

Find the area of the region that is inside the graph of r = 1 + sin θ and outside of the graph of r = 1.

anonymous · Answer

Im confused what exactly they are asking for. I can do the math

kainui · Answer

Well, I guess try to do as much as you can, pretend you know what to do and just start working something. Maybe try graphing it or setting up an integral?

anonymous · Answer

so i believe that the bounds of integration should be 0 to pi

anonymous · Answer

integral from 0 to pi of  (1/2) ((1+sin(theta))^2-1) dtheta

anonymous · Answer

right idea?

bobo-i-bo · Answer

Yup! you have the right idea, although your integral bounds are wrong. :P

anonymous · Answer

pi to 2pi maybe?

anonymous · Answer

not sure

bobo-i-bo · Answer

Draw the graph of the plots! :D It'll help

bobo-i-bo · Answer

Oh, sorry >.< You are completely right. The bounds are right.

anonymous · Answer

haha im right with my first bounds or with pi to 2pi?

anonymous · Answer

no worries

bobo-i-bo · Answer

First bounds are right.

bobo-i-bo · Answer

Lol, i drew the graph and found that the first bounds were right :P

anonymous · Answer

thank you. I appreciate the help!
