As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the values of \(x\) and ...

Algebraic structures form the backbone of many modern mathematical theories, with module theory standing as a central discipline within abstract algebra. Modules, generalising the concept of ...

Al-­Khwārizmī didn't write equations in the symbolic form we use today, either. In fact, to modern eyes his book is more arithmetical than algebraic, and one of its important impacts in Europe ...

who used the approach in an algebra class where many students fear math. “They were able to do it on their own.” The burst of pedagogical discussion about quadratic equations highlights the ...
