Question

The parametric coordinates of any point on the circle x2+y2-4 x-4 y=0 are- (A) (-2+2 cos α,-2+2 sin α) (B) (2+2 cos α, 2+2 sin α) (C) (2+2 √2 cos α, 2+2 √2 sin α) (D) (-2+2 √2 cos α,-2+2 √2 sin α)

Correct answer is (c) (2+2 √2 cos α, 2+2 √2 sin α)

Q. The parametric coordinates of any point on the circle $x^{2} + y^{2} - 4 x - 4 y = 0$ are-

$(- 2 + 2 cos α, - 2 + 2 sin α)$

$(2 + 2 cos α, 2 + 2 sin α)$

$(2 + 22 cos α, 2 + 22 sin α)$

$(- 2 + 22 cos α, - 2 + 22 sin α)$

Correct answer is (c) $(2 + 22 cos α, 2 + 22 sin α)$

Q. The parametric coordinates of any point on the circle x2+y2−4x−4y=0 are-

(−2+2cosα,−2+2sinα)

(2+2cosα,2+2sinα)

(2+22​cosα,2+22​sinα)

(−2+22​cosα,−2+22​sinα)
