quick maths question
by, 3rd December 2012 at 02:05 AM (327 Views)
alright, so I was doing my Calc 2 homework, and this problem came up:
Instructions: find the area of the region that lies inside both (polar) curves.
I'm given r^2=sin(2 * 'theta') and r^2=cos(2 * 'theta')
according to the back of the text book, I'm supposed to get (pi/8) - .25 at the end, but i'm not seeing how that answer is possible. I checked Yahoo answers, and found this-http://answers.yahoo.com/question/index;_ylt=Av1k8SdaO1Bjo9PtNMh8BogjzKIX;_ylv=3?qid=20120814143312AAHpW0X
but this doesn't get the answer in the book. I'm currently going to move on to another problem, and check this in a minute or so. In the meantime, all youse fellow math peeps should try to help me out...
