Question

Precalc:
Find all polar coordinates of point P where P =(4,-pi/3)

Answer 1

In that expression, what is r? what is (theta)?

Answer 2

i dont know, thats all im given

Answer 3

choices are
(4, -pi/ 3 + 2nπ) or (-4, -pi/ 3 + (2n + 1)π)

(4, -pi/ 3 + (2n + 1)π) or (-4, -pi/ 3 + 2nπ)

(4, -pi/ 3 + 2nπ) or (4, pi/3 + (2n + 1)π)

(4, -pi/ 3 + 2nπ) or (-4, -pi/ 3 + 2nπ)

Answer 4

so, to get this guy again, we just +2npi, that's it

Answer 5

@Bebong so d?

Answer 6

Let see!! now consider a) the first part matches with our logic, right? now, the second one
-4, -pi/3

Answer 7

(2n+1) pi = 2npi + pi
now, go around 2npi, we back to the same pot, right? 1 more pi
