Question

Determine the area of the inner loop of the polar curve r = 1 - 2sin(θ).

Answer 1

lol i had this question once
i knwo how to do it but its mad work

Answer 2

show me? :)

Answer 3

well 1st u need to graph it, that will find the intersections for the inner loop then use integral of 1/2 r^2, you can find half the interval since the graph is symmetric and not worry about the 1/2

Answer 4

graphing it is the annnoying part, for the inner loop problems you MUST graph it, findning the zeroes only wont work

Answer 5

well isnt it just a simple limacon curve? o.0
so not that difficult ..

Answer 6

well i get you
thnx :)
