MCQ

The parametric equations of the circle $x^2+y^2+m x+m y=0$ are

✓
$x=\frac{-m}{2}+\frac{m}{\sqrt{2}} \cos \theta_i y=\frac{-m}{2}+\frac{m}{\sqrt{2}} \sin \theta$
B
$x=\frac{-m}{2}+\frac{m}{\sqrt{2}} \cos \theta_2 y=\frac{+m}{2}+\frac{m}{\sqrt{2}} \sin \theta$
C
x = 0, y = 0
D
x = m cos θ, y = m sin θ

✓

Answer

Correct option: A.

$x=\frac{-m}{2}+\frac{m}{\sqrt{2}} \cos \theta_i y=\frac{-m}{2}+\frac{m}{\sqrt{2}} \sin \theta$

$x=\frac{-m}{2}+\frac{m}{\sqrt{2}} \cos \theta_i y=\frac{-m}{2}+\frac{m}{\sqrt{2}} \sin \theta$
