It is only a matter of time until each Engineering or Math student comes across the need to solve simultaneous equations. Fortunately, we live in a time when someone has already figured out the ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Systems of equations can be modelled as matrices in order to solve them The concept and example illustrated below explain the calculations that occur: $$ A \begin{bmatrix} x \\ y \\ z \end{bmatrix} = ...

A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns. They are a crucial part of linear algebra and have various applications in fields like engineering, ...

Equations that have more than one unknown can have an infinite number of solutions. For example, \(2x + y = 10\) could be solved by: \(x = 1\) and \(y = 8\) \(x = 2 ...

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

This carefully selected free compilation of exam questions has fully-worked solutions designed for students to go through at home, saving valuable time in class. Ideal for students who are revising ...
