Question

still about the polar curve
Hi,I was the guy who just asked the question about the polar curve.
what's the general way to find the limit of the polar curve,not just in the previous specific cause?For example,r=4+4sinΘ.It doesn't work if I set this function to zero.Please clear my confusion,thank you.
Yes.I can use my calculator.But,what features or functions do I use?

Answer 1

Can you use a graphing calculator?
If you can,then this problem is a simple one.
If you cannot,then you have to know how to sketch it.To sketch it,you can pick some special angles such as Θ = 0,30,45,60,90 etc.Since this graph has no inner loop,you can integrate it from 0 to 2pi to get the enclosed area.
