Be careful to note what a GCSE question is asking. If it states ‘solve algebraically’ then you must do so. To find solutions from graphs, look for the point where the two graphs cross one another.

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 ...

Differential equations are equations that contain derivatives. The equations are used in calculus to describe relationships among one or more variables. A solution to any series of equations can be ...

Okay, so I know that as soon as someone tells me what method to use, I'm gonna instantly remember it, but right now, I can think of only 1 way to solve simultaneous equations, and that doesn't work so ...

This paper uses a topic from multivariate analysis, i.e., canonical correlation theory, in the development of a generalized correlation coefficient for simultaneous equation systems. Canonical ...

During lockdowns, I researched viral internet maths sensations. Several of them are what a teenager might recognise as simultaneous equations. In the emoji example above, smiley faces = 4 and blown ...

Solving Maxwell’s equations, a set of four fundamental equations that define electromagnetism and optics, is fundamental to every task in computational photonics. Solving these equations for modern ...

Capture relationships between data sets by graphing linear equations in Microsoft Excel 2007. Linear equations allow you to predict values within your data set and view the overall trend. Use ...
