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

Linear functions, graphs and equations Linear functions are fundamental building blocks in mathematics and play a key role in solving real-world problems where the rate of change remains constant.

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.

Simultaneous equations can be solved algebraically or graphically. Knowledge of plotting linear and quadratic graphs is needed to solve equations graphically.

Find out how to solve simultaneous equations using a graph in this Bitesize KS3 maths video.

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 ...
