CHAPTER 34 - PLANE AREAS BY INTEGRAL
PROBLEM 15 -T
here .... the picture
find the area bounded by the given curve
note that this cardioid can also be represented by the equation
and the area of this cardioid is the same ...
... which leads me to believe that if you take the expressions for and , square each, and find their sum, you'll get .
I'll leave it for you to complete the necessary algebra/trig grunt work for confirmation.
thank you sir
I complete what you mention in the picture .. and I get the correct answer 6pi ,but to tell you the truth I haven`t study this way by using polar coordinates (if the teacher ask me why from 0 to pi !!! I have no idea).
but if you don`t mind I`ll show you what I did and give me your help ... 30 minutes later.
I am sorry about my English ..It isn`t my native language ... I am studying it
