Question

Determine two pairs of polar coordinates for the point (3, -3) with 0° ≤ θ < 360°

Answer 1

x = radius * cos(theta)
y = radius * sin(theta)

x = r*cos(theta)
y = r*sin(theta)

x^2 + y^2 = r^2, find r then plug in given x,y and r into the equations above to find theta, then you can express in polar coords, one will have a negative radius the other with have a positive radius

Answer 2

by negative radius i mean negative r

Answer 3

radial coordinate*
