Maximal arc

A Maximal arc in a finite projective plane is a largest possible (k,d)-arc in that projective plane. If the finite projective plane has order q (there are q+1 points on any line), then for a maximal arc, k, the number of points of the arc, is the maximum possible (= qd + d - q) with the property that no d+1 points of the arc lie on the same line.

Given the radius of a circle find the length of an arc

Learn how to solve problems with arcs of a circle. An arc is a curve made by two points on the circumference of a circle. The measure of an arc corresponds to the central angle made by the two radii from the center of the circle to the endpoints of the arc. The measure of the angle on a c

What is the definition of a tangent line to a circle

Learn the essential definitions of the parts of a circle. A secant line to a circle is a line that crosses exactly two points on the circle while a tangent line to a circle is a line that touches exactly one point on the circle. A chord is a line that has its two endpoints on the circle.

Parabolic Splines and Archimedes | Algebraic Calculus One | Wild Egg

We introduce parabolic splines associated to the parabola with simple Cartesian equation y=x^2. We look at two different situations, first evaluating signed areas of polygonal spline approximations to bigger and bigger portions of the curve, and then to a closer and closer examination of j
