helix
By integration. Divide the curve into small pieces, then add up the length of all the pieces.
elipse
yes but the figure is a closed curve. The distance around an object is the perimeter.
Technically yes; a curve with infinite radius.Technically yes; a curve with infinite radius.Technically yes; a curve with infinite radius.Technically yes; a curve with infinite radius.
Diameter is the length of a straight line passing through the center of a circle or sphere and connecting two points on the circumference of the circle or the surface of the sphere. Circumference is the length of the closed curve of a circle.
simple curve is a curve which doesnot cross itself,it neednot be closed....... but a simple closed curve is a curve which is simple and also closed. every simple closed curve is a simple curve but not vice versa.
region
Technically, yes.
An ellipse.
x(t)=t^2 , y(t)=t^3-t is a non-simple curve.
what is an non exsample of an perimrter
By integration. Divide the curve into small pieces, then add up the length of all the pieces.
Multiply the area squared minus the radius
No, it is not.
Ellipse and curve! apex
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
