Cone cutting sector from the point of the walkway.Each type of cone crop sector, it can be defined by using the directions of every point P on the trail must be based on specific properties, as follows:Circle: phases (P, C) = r, where C is the fixed point is called the Center and r is a constant, called the RADIUS,Parabola: phases (P, F) = distance (P, L), where F is the fixed point called the focal point and L is a straight line. Defines a fixed focal point has not passed and referred to the raketrik.Ellipse: term (P, A) + (B, P) = d, where B is A fixed point, two different points. The focal point is the so-called constant and d is greater than the distance (A, B) Is called the diameter.Hyperbolic: phases (P, A)-phase (P, B) = d, where B is A fixed point, two different points. Focal point and is called the d constant value that is less than the (A, B)
