A. Determine the equation of the circle with center (-1, 3) that contains the point (-4, -1). B. Then, identify two additional points that lie on the circle. Verify your answers by showing the coordinates satisfy the equation you created. Example 2: A. Determine the equation of the circle shown in the coordinate plane below. B. Then, identify three points that lie on the circle. Verify your
• The equation of a circle in the coordinate plane is x-h 2 + y-k 2 =r2, where r is the radius and h , k is the center of the circle. • Have a student give you any h , k , and r and show the circle in W|A.
• Equation of a circle: An equation of the circle with center (h, k) and radius r is given by (x − h)2 + (y − k)2 = r2 . This is called the standard form for a circle.

x2 + y2 = 1 x2 + y2 = 25 x2 + y2 = 64 The general equation of a circle is: →the centre of each of these circles is ( , ) →the x-intercepts are at x=
This is the standard form of the equation of a circle with will allow us to quickly identify the equation as that of a circle and to quickly identify the radius and center of the circle. Graphing circles is a fairly simple process once we know the radius and center. In order to graph a circle all we really need is the right most, left most, top most and bottom most points on the circle
EQuation of a Circle, Centre (0, 0) and Radius r A circle is a set of points (a locus) which are equidistant from a fixed point called the ‘centre’. The distance from the centre to any point on the circle is called the ‘radius’.
This is a PPT to cover the new GCSE topic of finding the equation of a tangent to a circle. It starts off with the circle with centre (0, 0) but as I have the top set in Year 11, I extended to more general circles to prepare them for A-Level maths which most will do.
Note:The general equation of the circle involves three constants which implies that at least three conditions are required to determine a circle uniquely . 11.1.3 Parabola A parabola is the set of points P whose distances from a fixed point F in the plane are equal to their distances from a fixed line l in the plane. The fixed point F is called focus and the fixed line l the directrix of the

example the graph of the equation x2 + y2 = a we know to be a circle, if a > 0. But if a 0, the graph is just the point (0; 0), and if a < 0, there is no graph. Similarly the equation x 2y = a describes a hyperbola if a 6 = 0, but if a 0, we get the two lines x y. First we list the standard forms of the basic curves. These are standard in the sense that any other curve given by a quadratic

The Unit Circle is the circle centered at the origin with radius 1 unit (hence, the “unit” circle). The equation of this circle is xy22+ =1. A diagram of the unit circle is shown below: We have previously applied trigonometry to triangles that were drawn with no reference to any coordinate system. Because the radius of the unit circle is 1, we will see that it provides a convenient
(1) If x c = y c = 0 (i.e. the centre of the circle is at origin) then equation of the circle reduce to x 2 + y 2 = r 2. (2) If r = 0 then the circle represents a point or a point circle. Perimeter of the Circle
