Graphing polar coordinates help??

OpenStudy (amilapsn):

yes?

OpenStudy (sharpsage):

\[(3,2\pi/3); (-3,2\pi/3)\]

OpenStudy (sharpsage):

I have no idea on how to do it

OpenStudy (amilapsn):

Have you an idea about Cartesian coordinate system?

OpenStudy (sharpsage):

Yeah I have a slight idea

OpenStudy (amilapsn):

Cartesian coordinate system is the normal (x,y) system... where you show the position of a point using rectangular coordinates. Likewise, any point in a plane can be shown through an angle from a fixed axis and a length from a fixed origin... Look @ this and you may be get an idea of polar coordinate system....|dw:1433473280875:dw|

OpenStudy (amilapsn):

|dw:1433473362776:dw| Can you tell me the polar coordinates of point A?

OpenStudy (sharpsage):

Is it \[(5,30°) or (5,\pi/6) \]

OpenStudy (amilapsn):

both are the same...

OpenStudy (sharpsage):

Ok got it

OpenStudy (amilapsn):

you can tell the angle in radians or degrees..

OpenStudy (sharpsage):

What do I do for the(−3,2π/3) coordinate where would I put that.

OpenStudy (amilapsn):

What do you do for the(3,2π/3) coordinate where would you put that?

OpenStudy (sharpsage):
