Essential understandings:

Calculus describes rates of change between two variables and the accumulation of limiting areas. Understanding these rates of change and accumulations allow us to model, interpret and analyze real-world problems and situations. Calculus helps us to understand the behaviour of functions and allows us to interpret the features of their graphs.

Suggested concepts embedded in this topic:

Change, patterns, relationships, approximation, generalization, space, modelling.

AHL: Systems, quantity.

Content-specific conceptual understandings:

• The derivative may be represented physically as a rate of change and geometrically as the gradient or slope function.

• Areas under curves can be can be approximated by the sum of the areas of rectangles which may be calculated even more accurately using integration.

• Examining rates of change close to turning points helps to identify intervals where the function increases/decreases, and identify the concavity of the function.

• Numerical integration can be used to approximate areas in the physical world.

• Mathematical modelling can provide effective solutions to real-life problems in optimization by maximizing or minimizing a quantity, such as cost or profit.

• Derivatives and integrals describe real-world kinematics problems in two and three-dimensional space by examining displacement, velocity and acceleration.

AHL

• Some functions may be continuous everywhere but not differentiable everywhere.

• A finite number of terms of an infinite series can be a general approximation of a function over a limited domain.

• Limits describe the output of a function as the input approaches a certain value and can represent convergence and divergence.

• Examining limits of functions at a point can help determine continuity and differentiability at a point.
