The points (x, y) of the unit circle are those that satisfy:
x2 + y2 = 1
or in parametric form:
x = cos t
y = sin t
as t varies from 0 to 2{pi} radians (= 360o)

An ant starts at the point 0 1 on the unit circle and walks around clockwise a distance of 6 units around the circle Find the x and y coordinates of the final location of the ant?
The ant is at (-0.2794, 0.9602)
Describe the coordinates of all points in all the quadrants?
The coordinates of all points in the coordinate plane consist of ordered pairs of numbers.
Why is the unit circle called two pi?
A unit circle is not normally called 2 pi. Because the radius length measure of the unit circle is 1 unit, then the circumference of a unit circle is 2*pi, and its area is pi.
How do you memorize the unit circle?
There really isn't much to memorize. The unit circle is a circle with a radius of 1.
A compass draws all points that are equidistant from a fixed point thereby creating a locus of points for a circle?
A circle is the locus of all points equidistant from a given point, which is the center of the circle, and a circle can be drawn with a compass. (The phrase "locus of points for a circle" does not seem to be conventionally defined.) or true
Find all the coordinates of the points on unit circle?
If x2 + y2 = 1, then the point (x,y) is a point on the unit circle.
What are the tangents of all coordinates in a unit circle?
WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?
What numbers have the absolute value of 1?
All complex number that can be represented by the coordinates of points on the unit circle, that is, the circle with its centre at the origin and a radius of 1 unit.
Is circle is a two dimensional figure?
Yes, the circle is a 2D object. All of its points only have X and Y coordinates.
What are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
Do you name a circle by the points on the circle Like a line segment is named by it's two end points how is a circle named By it's center Point?
You can completely specify a circle in a plane by giving the coordinates of its center point, and the length of the radius.
What is coordinates of points in the unit circle?
I'm not sure exactly what this question is asking, but I will attempt to answer. An angle on the unit circle is created by drawing a straight line from the origin to a point on the circle. The x-coordinate of a point corresponds to the cosine of the angle. For example: cos(90o) = 0 The y-coordinate of a point corresponds to the sine of the angle. For example: sin(270o) = -1
What is a center coordinate of 2 points known circle?
Knowing two points on a circle does not define a unique circle, so it is impossible to find the centre of the circle as there are infinitely many centres possible.
When the point xy is translated a unit to the leftthe coordinates of the new points can be determined by?
(x-1, y)
Coordinates of points on the unit circle?
Assuming you mean a unit circle with center at the origin, there are an infinite number of coordinate pairs on its circumference. The equation for the unit circle is: x2 + y2 = 1 and anycombination of (x,y) values that makes true will be your answer. The only integer answers are (1,0); (0,1); (-1,0) and (0,-1). Other solutions involve 'special angles' in trig but have irrational numbers and or fractions. 300 --> (1/2 , [sq root 3] / 2) 450 --> ([sq root 2] / 2 , [sq root 2] / 2) 600 --> ([sq root 3] / 2 , 1/2) any combinations of the above with opposite signs will also create coordinates for the unit circle.
How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
What are the coordinates of the midpoint of GH with end points?
-- The 'x' coordinate of the midpoint is the average of the 'x'-coordinates of the end-points. -- The 'y' coordinate of the midpoint is the average of the 'y'-coordinates of the end-points.
