Conic Section formulas are basically the formulas of ellipse, circle, hyperbola and parabola. All of these have

separate equations. For understanding the conic section formulas, one shall understand the basic concepts

of ellipse, circle, hyperbola and parabola.

For understanding purpose we can take one conic section example.

The conic section formula of circle is as follows:-

(x- h)^2 + (y-k) ^2 = r ^2

Here h, k are the centers of the circle

And r is the radius of circle.

Still for better understanding, some of the examples given below:-

10 cm.

That is h = 90 and k = 100

Also given the diameter of circle = 10 cm

We know that, Radius of circle = Diameter of circle/2 = 10/2 = 5 cm

Now we also know that the equation of circle is

(x- h)^2 + (y-k) ^2 = r ^2

So by substitution method,

(x- 90)^2 + (y- 100) ^2 = 5 ^2

20 cm.

That is h = 100 and k = 200

Also given the diameter of circle = 20 cm

We know that, Radius of circle = Diameter of circle/2 = 20/2 = 10 cm

Now we also know that the equation of circle is

(x- h)^2 + (y-k) ^2 = r ^2

So by substitution method,

(x- 100)^2 + (y- 200) ^2 = 10 ^2
