No, a circle graph is never a function.
a) A circle is not the graph of a function. b) A circle is not linear.
If you draw a unit circle, the sine function can be expressed as the y-coordinate of a point on the circle; the cosine function as the x-coordinate.
No, it is a shape rather than a function but it can be described using an algebraic function.
To qualify as a function, for every value of "x" there must be but a single "y" value. This isn't the case with a circle.
"a compass "But how do I write this mathematicaly?e.g.a parabula is f(x)=x2what is the way to write a circle function??
If a circle has radius r, then the area of the circle is pi r2, pi being about 3.14159. I beleive the function you are looking for is A(c)=c/2*r
The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
it means that the circle is either shrinking or expanding as time goes on
Circle
The function of the cerebal arterial circle (Circle of Willis) is protection. It provides alternate pathways for blood to reach the brain tissues in the case of arterial occlusion or impaired bloodflow anywhere in the system.
C = 2 x R x pi
