Double phase problems in elliptic equations represent a significant evolution in the study of nonlinear differential operators, characterised by the presence of two distinct growth phases within the ...

We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...

The unknown values in an equation could be the individual costs of a smoothie and a banana when the combined cost is known. Simultaneous equations can be useful when running a business. Watch the ...

A research team at Duke University has developed a new AI framework that can uncover simple, understandable rules that govern ...

Some important points to revise from the chapter are: • An equation of the form ax + by + c = 0, where a, b and c are real numbers, such that a and b are not both zero, is called a linear equation in ...
