This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1), x2,y2)&(x3,y3). Progra...

All those points for which the distance is greater than the radius of a circle lie in the exterior of the circle. For example points S and T lie on the exterior of the circle.All those points for which the distance is equal to that of the radius of a circle lie on the circle. For...
a circle is defined as a closed two-dimensional figure whose all the points in the boundary are equidistant from a single point (called centre). q2 what is the chord of a circle? the chord is a line segment that joins two points on the circumference of the circle. a chord only covers...

The equation of a circle through three points (x1,y1), (x2,y2), and (x3,y3) has this form: This is elegant equation, but it’s not in a form that’s ready to program. This post will start with the equation above and conclude with code. ...
Partitions of a plane, based on two or three of its points, are introduced. The study of these partitions is applied to finding the minimal enclosing circle (MEC) for a set S of n planar points. MEC(S), the MEC of n points of S, is defined by either a pair of S points with th...
A circle is defined by two parameters namely −Centre − It is a point inside the circle. All points on the circle are equidistant (same distance) from the centre point. Radius − The radius is the distance from the centre to any point on the circle. It is half the diameter....
2. What is the radius of the circle? 3. The tangent line to a circle may be defined as the line that intersects the circle in a single point called the point of tangency. Write the e At what points does the helix r(t) = (sin t, cos t, t...
