What are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
What is the circumference of a unit circle?
Since the radius of the unit circle is 1, the circumference is 2 x pi.
What is a cube whose edges measure 1 unit?
A 'unit cube'. Just like a circle with radius 1 and center at (0,0) is a 'unit circle'.
How sine is the y coordinate of a unit circle?
Sine is NOT the y coordinate: it is the sine of the angle made by the x-axis and the radius from a point on the circle. It is the cosine of the angle made with the y-axis.Consider any point, P, on the unit circle with coordinates (x, y). And let Q be the foot of the perpendicular from P to the x-axis. Then y = PQ.Now, in the right angled triangle OPQ, if OP makes an angle theta with the x axis, then sin(theta) = PQ/OP = y/OP and since OP is the radius of a unit circle, OP = 1 so that sin(theta) = y.
What is pi over 12 on a radian unit circle?
Pi over 12 on a radian unit circle is a little more than a quarter of the circle. Radian units are an alternative to degrees.
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.
Coordinates of the points in Unit circle?
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)
What are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
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
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)
When the point xy is translated a unit to the leftthe coordinates of the new points can be determined by?
(x-1, y)
What is the unit circle?
The unit circle is a circle that can be used to find trigonometric functions. The equation of the unit circle is x^2 + y^2 = 1. So it is any circle with radius 1.
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 to translate the coordinates of a point?
Here's an example: In the coordinate plane, the point is translated to the point . Under the same translation, the points and are translated to and , respectively. What are the coordinates of and ? Any translation sends a point to a point . For the point in the problem, we have the following. So we have . Solving for and , we get and . So the translation is unit to the right and units up. See Figure 1. We can now find and . They come from the same translation: unit to the right and units up. The three points and their translations are shown in Figure 2.
Can the unit circle have a radius of 2 unit?
If the radius is two. it won't be a unit circle, a unit circle is defined as a circle with radius one.
What are the four important points of the unit circle?
(0, 1) (1, 0) (0, -1) (-1, 0)
