Question

In polar form the equation of circle x2 + y2 = 4x is given by​

Answer 1

Answer:

hey! dear your answer in given below.

Step-by-step explanation:

Given equation of the circle is

x

2

+y

2

−4x+6y−12=0

⇒x

2

−4x+4+y

2

+6y+9=12+4+9

⇒(x−2)

2

+(y+3)

2

=5

2

The parametric coordinates of circle with the form (x−a)

2

+(y−b)

2

=r

2

is

(a+rcosθ,b+rsinθ) [θ being the parameter]

∴ The parametric coordinates of the given circle is

(2+5cosθ,−3+5sinθ)
