Domain And Range Of A Circle
A circle is a geometric shape consisting of points that are equidistant from a given point called center point.
Domain and range of a circle. Figure 2 range of values of trig functions. Assume the center is h k and the radius is r. Consequently the range of sine and cosine is the interval of 1. Domain of log x x 2 1 x 2 1 domain.
The range is more restricted. The domain is x l h r x h r the range is y l k r y k r for example if the center is 2 3 and the radius is 5 then the domain is from 3 to. To graph a circle visit the circle graphing calculator choose the implicit option. Domain and range tips for entering queries.
Find the domain of 1 e 1 x 1 function domain. Therefore the domain of the sine and cosine is the set of real values r. The domain of a circle is the x coordinate of the center of the circle plus and minus the radius of the circle. Since the circle is a unit circle for any angle both sine and cosine are within the range of minus one to plus one.
Michael j s answer is a good graphical demonstration of how the symmetry of a circle yields domains and ranges of equal span. It is easy to remember which coordinates domain and range refer to because x is alphabetically before y and domain is. To avoid ambiguous queries make sure to use parentheses where necessary. Square root of cos x.
The domain and range of a circle are constraint by the length of its radius and the. The cosine and sine are the abscissa and ordinate of a point that moves around the unit circle and they vary between 1 and 1. The range of a circle is the y coordinate of the center of the circle plus and minus the radius of the circle. It depends on two things the radius and the center.
The points of the circle belong to set r. This calculator will find either the equation of the circle from the given parameters or the center radius diameter area circumference perimeter eccentricity linear eccentricity x intercepts y intercepts domain and range of the entered circle. The domain and range of any real function is within the set of real numbers but we should narrow it down a bit. Here are some examples illustrating how to ask for the domain and range.
