This lesson focuses on defining a circle, presenting its equation in two different forms (standard and general), and giving examples of how to...
A unit circle from the name itself defines a circle of unit radius. A circle is a closed geometric figure without any sides or angles. The unit circle has all the properties of a circle, and its equation is also derived from the equation of a circle. Further, a unit circle is useful ...
How do you graph a circle equation? To graph a circle we need its equation to be in center-radius form. Then, we fix the sharp end of a compass at the center, with the legs at the radius distance and rotate the leg of the compass that has a pencil. How do you graph a circle...
Equation of a Circle
It is a 2-dimensional planar rounded geometry. Standard equation of a circle: $$\displaystyle (x-h)^2 +(y-k)^2 = r^2 $$ Here {eq}(h,k) {/eq} are the coordinates of the center and {eq}r {/eq} is the radius of the circle. ...
General Equation of a Circle Definition A circle is defined as the locus of a point that moves in a plane such that its distance from a fixed point in that plane is always constant. The fixed point is called the centre of the circle and the constant distance is called the radius of the...
Equation of a cirle. How to express the standard form equation of a circle of a given radius. Practice problems with worked out solutions, pictures and illustrations.
Which of the following equations has a graph that is narrower than the graph of y = 2x^2 + 3? (a) y = 2x^2 - 3 (b) y = 3x^2+ 2 (c) y = 0.5x^2 + 3 (d) y = 0.5x^2 - 2 What is the definition of endpoint in geometry?
