Question about linear programming

AI Thread Summary
The discussion centers on three linear equations, y1, y2, and y3, that intersect at a common point. The area between the curves y1 and y2 from 0 to the intersection is identified as the "feasible region," particularly in economic applications. While the feasible region is acknowledged, the conversation shifts to the utility of calculating its actual size. Determining the size of this region can provide insights into resource allocation and optimization in economic models. Understanding the area can enhance decision-making processes within the context of the specific application.

basically, let's say i have three linear equations, y1, y2, and y3.

assume y1 = ax+b where a and b are constants
assume y2 = mx+k where m and k are constants
assume y3 = n where n is a constant

also, now assume that they all intersect at y1=y1=y3=n.

would the area between the curves, y1 and y2, from 0 to the intersection represent anything? I've attached a sample pic for reference.

Wow, I think I repeating what I just said in the previous thread! What anything in mathematics "represents" depends upon the specific application. In economics that area is commonly referred to as the "feasible region" because it is, by the terms of the application that gives you those equations, the area in which a solution must occur.
 
well...i know it's the feasible region. But let's stick with the economics example...does computing the actual size of that region give anything useful?
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
