If the Cartesian co-ordinates of a point are ( -5 3 2 , 5 2 ) , then its polar co-ordinates are

Options

  1. A(5, 2 3 )
  2. B(5, 13 18 )
  3. C(5, 5 6 )
  4. D(5, 11 18 )

Correct answer

C. (5, 5 6 )

Step-by-step solution

aligned & r= x^2+y^2 = 75 4 + 25 4 =5 & = - ⁻¹ | y x |= - ⁻¹ ( 1 3 )= - 6 = 5 6 & Polar co-ordinate =(r, )= (5, 5 6 ) aligned
