Firstly, we need to differentiate the function of the curve y = x^3 + 2x^2 - 5. Using d/dx (x^n) = nx^(n - 1), we get dy/dx = 3x^2 + 4x. To find the gradient of this curve, we then need to evaluate dy/dx ...

Let f(x) = x²- 1To apply a vertical translation, simply add the value to the overall equation. In this case it is p...

Standard form is a way of writing really big numbers in what is often a more compact manner. It also makes a really large number more readable. To put a number in standard form we write it by having a num...

The derivative is calculated by multiplying by the degree of the variable then taking taking away 1 from the degree.So to calculate the derivative of x^2 we multiple the variable (which is x) by the degre...

To solve simultaneous equations you need to cancel out variables like x and y one at a time to solve for the other. In the edexcel GCSE 2017 paper this question came up: solve simultaneously x²...
