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.
What does degrees mean?
I assume this question refers to either geometric degrees or to temperature measurements. (Not diplomas awarded by post-secondary institutions.) In geometry, a degree is a unit of measure of an angle formed by two intersecting lines. It is defined as 1/360th of a full circle. A quarter of a circle forms a right angle (think 12 o'clock to 3 o'clock) and 90/360 equals 1/4, so a right angle is 90 degrees. When measuring temperature, there are two main types of degree, Fahrenheit and Celsius. A Celsius degree is larger, meaning it measures a greater difference in temperature than one degree Fahrenheit, the ratio being 9 to 5 or 1.8.
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.
A unit for measuring an angle or an arc of a circle?
Radian = (180/pi)o
What is standard unit of measuring an angle?
Degrees of a full circle of 360 degrees.
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)]
Why does the unit circle become the basis of a unit function?
It can be the basis of the trig functions because the hypotenuse, which is the radius, is 1. For related reasons, it can represent unit vectors in any direction.
