Please check my answers I really need to do my homeowrk!;This are polar coordinates we're studying-I'm almost positive the first two are correct.
1.Which of the folowing is another representation of (-3,pi)?
(3,0 degree)I think it is this one??
2.Which is not a representation of (5,150 degree)
(-5,-30 degree)I think it is this one?
3.Give 3 representations of (3,240 degree)One has to be in radians
My choices are: (3,600 degrees)
(3,-120 degree degree)
4.Give 3 representations of (-6,3pi/4)one has to be radians
I gave-(-6,495 degrees)
