Simpson's rule Consumer Problem with Hicksian demand
What is the meaning of least squares in a regression model?
DEFINITION of 'Least Squares' Least squares is a statistical method used to determine a line of best fit by minimizing the sum of squares created by a mathematical function. A "square" is determined by squaring the distance between a data point and the regression line.

The trapezoidal rule and Simpson's rule.
Simpson's rule is a Newton-Cotes formula for approximating the integral of a function using quadratic polynomials (i.e., parabolic arcs instead of the straight line segments used in the trapezoidal rule).

The Consumer Problem
The Structure of Applied General Equilibrium Models
By Victor Ginsburgh, Michiel Keyzer
In microeconomics, a consumer's Marshallian demand function (named after Alfred Marshall) specifies what the consumer would buy in each price and income or wealth situation, assuming it perfectly solves the utility maximization problem.

My neighbor is from the Marshall Islands and his great grandfather was Kai BooKee, the highest chief, his father served in WWii in Guadalcanal in the Army and he worked for a government contractor called the Transport Company of Texas in the 1960's as well with other government contractors between the 1960's and 1990's. His cousin was a former president of the Marshall Islands. He has helped me to a measurable degree with my research as a Small Business of Innovation Research, certified with the US as well as Texas HUB and Austin MBE, doing business as Serenity Sells.

The Marshallese expression 'unare peim' translates as 'heap the labors of your hands' or reap what you sow. Thanks neighbor Andrew.
Marshallian and Hicksian demands
Why is Hicksian demand steeper than marshallian?
The Hicksian demand is steeper than the Marshallian Demand because the Hicksian Demand only accounts for substitution effects while the Marshallian Demand focuses on income and substitution effects.

The Heckscher–Ohlin model (H–O model) is a general equilibrium mathematical model of international trade, developed by Eli Heckscher and Bertil Ohlin at the Stockholm School of Economics. It builds on David Ricardo's theory of comparative advantage by predicting patterns of commerce and production based on the factor endowments of a trading region. The model essentially says that countries export products that use their abundant and cheap factors of production, and import products that use the countries' scarce factors.

What would Homer from the Simpsons say?
(/doʊʔ/) is a catchphrase used by the fictional character Homer Simpson, from one of the longest running American animated sitcom The Simpsons (1989–present). It is typically used when Homer injures himself, realizes that he has done something stupid, or when something bad has happened or is about to happen to him
In mathematics, the modular group is the projective special linear group PSL(2,Z) of 2 x 2 matrices with integer coefficients and unit determinant. The matrices A and -A are identified. The modular group acts on the upper-half of the complex plane by fractional linear transformations, and the name "modular group" comes from the relation to moduli spaces and not from modular arithmetic.
In abstract algebra, the sedenions form a 16-dimensional noncommutative and nonassociative algebra over the reals obtained by applying the Cayley–Dickson construction to the octonions. Unlike the octonions, the sedenions are not an alternative algebra. It is possible to apply the Cayley-Dickson construction to the sedenions infinitely on, but the algebras created have the same properties as sedenions and are of little interest.
The term sedenion is also used for other 16-dimensional algebraic structures, such as a tensor product of two copies of the biquaternions, or the algebra of 4 by 4 matrices over the reals, or that studied by Smith (1995).
In mathematics, the Cayley–Dickson construction, named after Arthur Cayley and Leonard Eugene Dickson, produces a sequence of algebras over the field of real numbers, each with twice the dimension of the previous one. The algebras produced by this process are known as Cayley–Dickson algebras, for example complex numbers, quaternions, and octonions. These examples are useful composition algebras frequently applied in mathematical physics.
The Cayley–Dickson construction defines a new algebra similar to the direct sum of an algebra with itself, with multiplication defined in a specific way (different from the multiplication provided by the genuine direct sum) and an involution known as conjugation. The product of an element and its conjugate (or sometimes the square root of this product) is called the norm.
The symmetries of the real field disappear as the Cayley–Dickson construction is repeatedly applied: first losing order, then commutativity of multiplication, associativity of multiplication, and next alternativity.
More generally, the Cayley–Dickson construction takes any algebra with involution to another algebra with involution of twice the dimension.

(mathematics) A 32-dimensional hypercomplex number that is a nonassociative extension of a sedenion.
A trigonometric equation is one in which the unknown to be solved for is an angle (call it θ) and that angle is in the argument of a trigonometric function such as sin, cos or tan.
What is the argument in math?
In mathematics, an argument of a function is a specific input in the function, also known as an independent variable. When it is clear from the context which argument is meant, the argument is often denoted by the abbreviation arg.
In mathematics, Dedekind cuts, named after German mathematician Richard Dedekind, are а method of construction of the real numbers from the rational numbers. A Dedekind cut is a partition of the rational numbers into two non-empty sets A and B, such that all elements of A are less than all elements of B, and A contains no greatest element. The set B may or may not have a smallest element among the rationals. If B has a smallest element among the rationals, the cut corresponds to that rational. Otherwise, that cut defines a unique irrational number which, loosely speaking, fills the "gap" between A and B. In other words, A contains every rational number less than the cut, and B contains every rational number greater than or equal to the cut. An irrational cut is equated to an irrational number which is in neither set. Every real number, rational or not, is equated to one and only one cut of rationals.
Dedekind cuts can be generalized from the rational numbers to any totally ordered set by defining a Dedekind cut as a partition of a totally ordered set into two non-empty parts A and B, such that A is closed downwards (meaning that for all a in A, x ≤ a implies that x is in A as well) and B is closed upwards, and A contains no greatest element. See also completeness (order theory).
It is straightforward to show that a Dedekind cut among the real numbers is uniquely defined by the corresponding cut among the rational numbers. Similarly, every cut of reals is identical to the cut produced by a specific real number (which can be identified as the smallest element of the B set). In other words, the number line where every real number is defined as a Dedekind cut of rationals is a complete continuum without any further gaps.
A similar construction to that used by Dedekind cuts was used in Euclid's Elements (book V, definition 5) to define proportional segments.
In mathematics, a hypercomplex number is a traditional term for an element of a unital algebra over the field of real numbers. The study of hypercomplex numbers in the late 19th century forms the basis of modern group representation theory.
