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.
Who made the unit circle?
It is unknown who created the unit circle. Pythagoras did a lot of work related to the unit circle. In ancient times, Greek, Indian, and Arabian mathematicians used 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 is the history of unit circle?
Here is a time-line that shows the history of the unit circle dating back to 250 B.C.
In a unit circle what quadrant is 7 in?
1
What is the equation of a unit circle?
A unit circle is a circle of radius 1. If it's center is at the origin of an xy-coordinate system, then the equation is x (squared) + y (squared) = 1
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.
What is standard unit of measuring an angle?
Degrees of a full circle of 360 degrees.
A unit for measuring an angle or an arc of a circle?
Radian = (180/pi)o
How can the radian measure of an angle determine the arc length on the unit circle?
The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.
What is the equation of the unit circle?
For a circle with center at (a,b), and radius r: (x-a)2 + (y-b)2 = r2
How can one calculate the area of a unit circle?
To calculate the area of a unit circle you should use the equation x2+y2=1. The unit circle equal area of 1. You can find out more information on the mathisfun website for deeper explanation.
Which unit does a circle patch with an arrow represent?
You may mean the symbol for male, if so then the symbol for female is a circle patch with a cross.
What is the meaning of radian system?
The radian system describes angles in terms of the diameter of a unit circle, i.e. where the radius is 1. If two lines intersect at the radius of a unit circle, the angle in radians between those two lines is the length of the arc along the diameter of the circle delimited by those two lines. The diameter of a unit circle is 2 pi. In the degree system, the angle of one quarter of the circle is 90, while the radians of that same angle is pi / 2. One radian is approximately 57.3 degrees.
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 are the coordinates of the point of intersection of the angle -225 and the unit circle?
[-sqrt(2), -sqrt(2)]
What is the unit used to measure distances around a circle?
Radian is the unit used to measure distances around a circle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.
