Am I Right???

OpenStudy (ohohaye):

I'm pretty sure that I'm right but, I just want to double check

OpenStudy (ohohaye):

@sdfgsdfgs

OpenStudy (anonymous):

how did you get 4pi/3

OpenStudy (sdfgsdfgs):

-4pi/3 will be in the second quadrant so the angle is right.... but r=-2 which will put the point back in which quadrant?

OpenStudy (ohohaye):

Oh I actually meant to put the second one

OpenStudy (sdfgsdfgs):

is the angle correct in the second choice?

OpenStudy (anonymous):

oh ok i see didnt notice the negative

OpenStudy (ohohaye):

Ugh, mean the last one sorry

OpenStudy (sdfgsdfgs):

hahahaaa plz dont tell me u are guessing plz? ;)

OpenStudy (sdfgsdfgs):

but yes d is the right ans

OpenStudy (anonymous):

there is only one obvious choice here

OpenStudy (ohohaye):

O wait actually I did mean to choose that one because it is the only one that has a negative

OpenStudy (anonymous):

there cant be a negative value for the first point because it is radius

OpenStudy (ohohaye):

oh I though it was a kind of pi chart

OpenStudy (sdfgsdfgs):

just remember in polar coord, pi=180deg. when it gets confusing, just convert the angle back to degree to see where the point is :)

OpenStudy (ohohaye):

Ok, thank you
