The Unit Circle The Unit Circle Written by tutor ShuJen W. The above drawing is the graph of the Unit Circle on the X – Y Coordinate Axis. It can be seen from the graph, that the Unit Circle is defined as having a Radius ( r ) = 1. Going from Quadrant I to Quadrant IV, counter clockwise, the Coordinate points on the axis of the Unit Circle are: (1, 0), (0, 1), (-1, 0), and (0, -1) This is important to remember when we define the X and Y Coordinates around the Unit Circle. The Unit Circle has 360°.

Circle Equations And that is the Standard Form for the equation of a circle! It shows all the important information at a glance: the center (a,b) and the radius r. Example: A circle with center at (3,4) and a radius of 6: Start with: (x−a) 2 + (y−b) 2 = r 2. Put in (a,b) and r: (x−3) 2 + (y−4) 2 = 6 2. We can then use our algebra skills to simplify and rearrange that equation, depending on what we need it for.

A circle is the set of all points in a plane equidistant from a fixed point called the center point . We can derive the equation directly from the distance formula. If we place the center point on the origin point, the equation of a circle with center point (0, 0) and radius r is: See 1.6.  (x2 - 8x + 16) + (y2 + 4y + 4) = 8 + 16 + 4.  (x - 4)2 + (y + 2)2 = 28 Now it's in the correct form!!  Center point (4, -2) with radius = The graph is:  3) Find the intersection of the line y = x - 1 and the circle x2 + y2 = 25.  Solution: A line could intersect a circle twice or once (if it is tangent) or not intersect at all. To find the intersection use substitution. Replace y in the circle equation with x - 1.

- The answer to the latter question is Archimedes. The form in which Archimedes stated it was that the area of a circle is equal to that of a right triangle whose base is the circumference of the circle, and whose height is the radius of the circle. That is, A = 1/2 (2 pi r) r = pi r^2 in modern terms.
