A double-end Euler spiral. The curve continues to converge to the points marked, as t tends to positive or negative infinity. An Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). This curve is also referred to as a clothoid or Cornu spiral.
Selected witch of Agnesi curves (green), and the circles they are constructed from (blue), with radius parameters =, =, =, and =.. In mathematics, the witch of Agnesi (Italian pronunciation: [aɲˈɲeːzi,-eːsi;-ɛːzi]) is a cubic plane curve defined from two diametrically opposite points of a circle.
Cissoid of Diocles traced by points M with ¯ = ¯ Animation visualizing the Cissoid of Diocles. In geometry, the cissoid of Diocles (from Ancient Greek κισσοειδής (kissoeidēs) 'ivy-shaped'; named for Diocles) is a cubic plane curve notable for the property that it can be used to construct two mean proportionals to a given ratio.
Examples of superellipses for =, =. A superellipse, also known as a Lamé curve after Gabriel Lamé, is a closed curve resembling the ellipse, retaining the geometric features of semi-major axis and semi-minor axis, and symmetry about them, but defined by an equation that allows for various shapes between a rectangle and an ellipse.
Graphs of roses are composed of petals.A petal is the shape formed by the graph of a half-cycle of the sinusoid that specifies the rose. (A cycle is a portion of a sinusoid that is one period T = 2π / k long and consists of a positive half-cycle, the continuous set of points where r ≥ 0 and is T / 2 = π / k long, and a negative half-cycle is the other half where r ...
Animation showing curve adaptation as the ratio a / b increases from 0 to 1. The animation shows the curve adaptation with continuously increasing a / b fraction from 0 to 1 in steps of 0.01 (δ = 0). Below are examples of Lissajous figures with an odd natural number a, an even natural number b, and | a − b | = 1.
The following are usually easy to carry out and give important clues as to the shape of a curve: Determine the x and y intercepts of the curve. The x intercepts are found by setting y equal to 0 in the equation of the curve and solving for x. Similarly, the y intercepts are found by setting x equal to 0 in the equation of the curve and solving ...
Devil's curve for a = 0.8 and b = 1. Devil's curve with ranging from 0 to 1 and b = 1 (with the curve colour going from blue to red).. In geometry, a Devil's curve, also known as the Devil on Two Sticks, is a curve defined in the Cartesian plane by an equation of the form [1]
