Differentiation (Edexcel A-Level Mathematics): Flashcards

Differentiate to get $\frac{dy}{dx} = 2x$.

The chord becomes a tangent to the curve.

The gradient is given by $nx^{n-1}$.

The gradient is $4x^3$.

It represents the gradient of the function at a point.

Find the limit of $(f(x+h) - f(x)) / h$ as $h$ approaches $0$.

It is also called the derivative.

It represents the rate of change of $y$ with respect to $x$.

The gradient is $3x^2$.

$dy/dx = 6x + 2$
