Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

In this repositoy there are two packages that allow to solve systems of polynomial inequalities. The package DisSolve.m2 is a Macaualy2 package to solve numerically systems of polynomial inequalities.

so correct answer should be greater than π/4 means(0.788079176244539 ) not greater than or equal. Extended answers is : π/4 + 2k.π < x < 3 π/4 + 2k.π ,where k = 0,1,2,.. so it is returning answer ...

Abstract: Guessing games for directed graphs were introduced by Riis for studying multiple unicast network coding problems. In a guessing game, the players toss generalised dice and can see some of ...

Abstract: A marginal problem asks whether a given family of marginal distributions for some set of random variables arises from some joint distribution of these variables. Here, we point out that the ...
