Question

Determine two pairs of polar coordinates for the point (2, -2) with 0° ≤ θ < 360

Answer 1

Jut pick them out! Polar coordinates look like this: \((r,\theta)\)

I'll do the hard one. You do the easy one.

\((-2\sqrt{2},3\pi/4)\;or\;(-2\sqrt{2},135º)\)

Answer 2

wait im sorry what

Answer 3

@hartnn you have any idea?

Answer 4

x=2,y=-2
r = \sqrt (x^2+y^2)
theta = arctan(y/x)

Answer 5

ok what does that mean xD?

Answer 6

i just gave you formulas,
you had a point x,y = 2,-2
to convert it into polar , we use this formulas
r = \sqrt (x^2+y^2)
theta = arctan(y/x)
and then polar co-ordinate will be r, theta
