What is Differentiation?

We use differentiation to generally find the rate of change for a function. This could also be interpreted as finding the gradient of a curve. e.g. y = x ^ 2.

If you consider the curve, it has a different gradient at various points. We could draw a tangent at the point however a more accurate answer would be to differentiate.

There is a simple method to differentiate curves. We denote the differential of y as dy/dx.
