degree of curve
41Butterfly curve (algebraic) — In mathematics, the algebraic butterfly curve is a plane algebraic curve of degree six, given by the equation :x^6 + y^6 = x^2. The butterfly curve has a single singularity with delta invariant three, which means it is a curve of genus seven. The …
42Crooked egg curve — In algebraic geometry, a curve which has been called the crooked egg curve, and also the bean curve , is a plane algebraic curve of degree four and genus zero, with equation:(x^2+y^2)^2=x^3+y^3 ,.The equation can also be given in polar form, as:r …

44Laffer curve — In economics, the Laffer curve is used to illustrate the idea that increases in the rate of taxation may sometimes decrease tax revenue. Since a 100 percent income tax will generate no revenue (as citizens will have no incentive to work), the… …
45Oxygen-haemoglobin dissociation curve — The oxygen haemoglobin dissociation curve plots the proportion of hemoglobin in its saturated form on the vertical axis against the prevailing oxygen tension on the horizontal axis. The oxyhemoglobin dissociation curve is an important tool for… …
46Oxygen–haemoglobin dissociation curve — The oxygen–haemoglobin dissociation curve (or oxygen–hemoglobin dissociation curve) plots the proportion of haemoglobin in its saturated form on the vertical axis against the prevailing oxygen tension on the horizontal axis. The oxyhaemoglobin… …
47Gonality of an algebraic curve — In mathematics, the gonality of an algebraic curve C is defined as the lowest degree of a rational map from C to the projective line, which is not constant. In more algebraic terms, if C is defined over the field K and K ( C ) denotes the… …
48Hubbert curve — The Hubbert curve projects the rate of oil production over time, and is the main component of Hubbert peak theory. It was first proposed by geophysicist M. King Hubbert in the mid 1950s during his tenure at the Shell Oil Company. [cite journal |… …
49Deltoid curve — The red curve is a deltoid. In geometry, a deltoid, also known as a tricuspoid or Steiner curve, is a hypocycloid of three cusps. In other words, it is the roulette created by a point on the circumference of a circle as it rolls without slipping… …
50Minimum railway curve radius — 90 foot (27.43 m) radii on the elevated 4 ft 8 1⁄2 in (1,435 mm) Chicago L . There is no room for longer radii at this street intersection The minimum railway curve radius, the shortest design radius, has an… …
