The derivative may be represented physically as a rate of change and geometrically as the gradient or slope function.
I can explain the relationship between a function, its derivative and the second derivative in terms of maxima, minima, points of inflexion and roots.
I can discuss graphical behaviour of functions, including the relationship between the graphs of f, f' and f"
I can sketch functions and derivatives when given a derivative, a second derivative or function as a graph
Sign diagrams are used to find out on what intervals functions are positive and negative. This is important to know when working with derivative functions.
Show the includes the second derivative
Print and cut the cards. Then sort the cards in matching groups of 4:
The graph with its function and the derivative with its graph
This one is a bit trickier and can be used as an extension
Activity: Finding the function from a graph for quadratics and cubics. Derivative calculus. Equation of tangents. Systems of equations.
