Solving an equation means finding the value or values for which the two expressions on each side of the equals sign are equal. One of the most common methods used to solve equations is the balance ...

A number machine is a way of writing rules using a flow diagram. The equation \(3j - 6 = 9\) can be shown on a number machine by writing out the functions that have been applied to \(j\) in the order ...

Abstract: The question of inverting linear time-invariant dynamical systems has been of interest to control engineers for many years. An example of the nonstate-variable approach and application of ...

Abstract: This article investigates the distributed optimal output consensus problem of heterogeneous linear multiagent systems over weight-unbalanced directed networks. A novel distributed continuous ...

2024 was the warmest year in the 175-year observational record. It was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of ...
