Protons minimize energy by forming pairs with opposite spin. Same for neutrons. Each pair acts like a particle in its own right. So nuclei act very differently depending on whether they have an even ...

His work involves the use of algebra to investigate geometry and symmetry, and has focused on using those ideas to find solutions for differential equations ... involving linear PDEs, was done ...

This section focuses on the key features and methods for working with linear graphs. It demonstrates how to sketch graphs from rules, derive rules from graphs, and calculate key features such as the ...

They provide a versatile framework for solving equations, visualising data, and making informed decisions. This resource revises linear functions, graphs and equations and within linear functions, ...

In quadratic equation, students are expected to find the relation between two variable given in the two equation. The related can be of Smaller to, Greater to, Greater than, Smaller than and Equal to.
