The polar co-ordinates of the point whose cartesian co-ordinates are (-2,-2) , are given by

Options

  1. A(2 2 , 5 4 )
  2. B(2 2 , 3 4 )
  3. C(2 2 , 7 6 )
  4. D(2 2 , 4 )

Correct answer

A. (2 2 , 5 4 )

Step-by-step solution

(C) We know that r= x²+y² = (-2)²+(-2)² =2 2 and = y x = -2 -2 =1 = ⁻¹ 1= ( + 4 )= 5 4 , as the point (-2,-2) lies in III quadrant. (r, )= (2 2 , 5 4 )
