Question

Plot the point given in polar coordinates and find other polar coordinates (r,theta) for the point for which: 
A) r>0, -2pi is less than or equal to theta which is <0

B) r<0, 0 is less than or equal to theta <2pi

Please help me :(

anonymous · Answer

hmm... r is the absolut value. As much as I know it can't be <0

anonymous · Answer

r is the distance from the origin, so it can't be negative

anonymous · Answer

what is the answer?

kropot72 · Answer

The answer to B) is :
There can be no point the reason being that r must be positive.

anonymous · Answer

the answer is 
A= 5,-4pi/3

B= -5,5pi/3

I have no idea how they did this

anonymous · Answer

Whats the point given? Or does it not list one?

anonymous · Answer

the point is (5pi,2pi/3)
