Question

I'm learning about complex numbers. How do I write 5pi/6 in polar form and make sure the radius is a positive value?

Answer 1

Is that all your given is 5pi/6?

Answer 2

Well I am given a graph with to plotted lines but I am asked to find the polar form of one of them. Would it be easier if I drew the graph?

Answer 3

Does it give you the equation of the line?

Answer 4

yes, it is on the 4th line

Answer 5

That's all it gives ya, eh? Well, polar form is (radius, theta). But it looks like you already have a theta if you have 5pi/6 and pi/4

Answer 6

5pi/6 and pi/4 are two different questions. How would I put it in the polar form?

Answer 7

I know. I'm just saying that when you have an angle like pi/4, it already is polar form. All you need is a radius. So your line that is with 5pi/6. If that extended out to the 3rd circle, it would have a radius of 3, in which case it is just (3, 5pi/6) as a polar coordinate. Or am I missing what your asking? lol x_x

Answer 8

okay so since it goes out to the 4th circle, the answer would be (4, 5pi/6), right?

Answer 9

Right.

Thanks so much! :)

Answer 12

@Psymon could you help me with one more question? :)
