Question

write parametric equation of circle (x-3)²+(y+4)²=25
​

Answer 1

The equation of the circle is(x − 3)² + (y + 4)² = 25 -Comparing this equation with (x-h)² +(y-k)² = r²,we get, h = 3, k = - 4 and r = 5

The parametric representation of the circle is

he parametric representation of the circle isx = h + r cos 0, y = k + r sin 0

i.e, x = 3+5 cos0 , y = k + r sin0

Hope this helps you, Stay home stay safe☺️
