Differentiation is process of finding rates of change of one quantity compared to another. We need differentiation when the rate of change is not constant. Also it is process of finding derivative from function. As well as gradient of tangent to the curve. Differentiation (Power Rule)
This post about the sketching of curve though coordinate of turning and axes intercepts . So equation of the curve is given. Curve sketching
This post about tips to sketch derivative curve from curve . Therefore, we have to analyse curve like their intercepts , stationary point slope . derivative curve
