ALL meanings of conchoid
con·choid
C c - noun conchoid a plane curve consisting of two branches situated about a line to which they are asymptotic, so that a line from a fixed point (the pole) intersecting both branches is of constant length between asymptote and either branch. Equation: (x – a)2(x2 + y2) = b2x2 where a is the distance between the pole and a vertical asymptote and b is the length of the constant segment 3
- noun conchoid a curve traced by an end point of a segment of constant length located on a straight line that rotates about a fixed point, while the other end point moves along a straight line that does not go through the fixed point 3
- noun conchoid a plane curve such that if a straight line is drawn from a certain fixed point, called the pole of the curve, to the curve, the part of the line intersected between the curve and its asymptote is always equal to a fixed distance. Equation: r = b ± a sec(θ). 1
- noun conchoid (mathematics, geometry) Any of a family of curves defined as the locus of points p, such that each p is on a line that passes through a given fixed point P and intersects a given curve, C, and the distance from p to the point of intersection with C is a specified constant (note that for nontrivial cases two such points p satisfy the criteria, and the resultant curve has two parts). 0
- noun conchoid (geology) A conchoidal fracture in rock. 0
