Circle in math equation

A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center. The equation of a circle with (h, k) center and r radius is given by: (x-h)2+ (y-k)2= r2 This is the standard form of the equation. … See more Consider an arbitrary point P(x, y) on the circle. Let ‘a’ be the radius of the circle which is equal to OP. We know that the distance between the … See more Let C(h, k) be the centre of the circle and P(x, y)be any point on the circle. Therefore, the radius of a circle is CP. By using distance formula, (x-h)2 + (y-k)2 = CP2 Let radius be ‘a’. Therefore, the equation of the circle … See more To find the polar form of equation of a circle, replace the value of x = r cos θ and y = r sin θ, in x2 + y2 = a2. Hence, we get; (r cos θ)2 + (r sin θ)2 = a2 r2 cos2 θ + r2 sin2 θ = a2 r2 … See more The general equation of any type of circle is represented by: x2+y2+2gx+2fy+c = 0, for all values of g, f and c. Adding g2+f2on both sides of the equation gives, x2+2gx+g2+y2+2fy+f2= g2+f2−c………………(1) Since, (x+g)2 = x2+ 2gx + g2 and (y+f)2 =y2 + 2fy + f2substituting … See more WebExpand this expression to get the required equation of the circle. ⇒ x2 + a2 – 2ax + y2 + b2 – 2by = a2. ⇒ x2 + y2 – 2ax – 2by + b2 = 0. It can be written as follows. ⇒ x2 + y2 – 2 …
