Question

Convert (-3, 3) to polar coordinates with r positive and u between 0 and 2p.

Expert Solution
Step 1

Given point in cartesian co-ordinate system:

                              (-3, 3)

Step 2

To convert from Cartesian Coordinates (x, y) to Polar Coordinates (r,θ):

  • r=x2+y2

and θ is given quadrant wise as below:

Quadrant   (x, y)     θ in radian
I x>0, y>0 tan-1yx
II x<0, y>0 π+tan-1yx
III x<0, y<0 π+tan-1yx
IV x>0, y< 0 2π+tan-1yx
