By this block we should be starting Differentiation.

The derivative of a function of a real variable measures the sensitivity to change of a quantity (a function value or dependent variable) which is determined by another quantity (the independent variable). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time is advanced.

Khan Academy has a great resource on Differentiation.

The year plan is as follows:

• Trigonometry - internal assessment 91575 4cr
• Differentiation - external assessment 91578 6cr
• Integration - external assessment 91579 6cr
• Complex Numbers - external assessment 91577 5cr

I suggest all students revise basic algebra as it is the language we will be using in this course to learn more complex ideas.
Maybe create a khanacademy login and practise - you can join the rest of the class on there with this code 5E2XNC
These are the two key areas to be well practised at.
