## Grade 12 Chapter 7 – Finance

Use this chapter to study all things related to finance, from simple and compound interest, depreciation and effective interest rates, to learning about future-value annuities and present-value annuities. This chapter has great tips and hints and has a summary exercise at the end to help you with your exams. Download here: Chapter 7 – Finance

## Grade 12 Chapter 6 – Linear Programming

Linear programming is about using straight line graphs to optimise (in other words find the maximum or minimum) solution for a number of constraints. We show how to find the constraints, how to draw the constraints onto the Cartesian plane and how to find the profit or loss. There are lots of great examples for […]

## Grade 12 Chapter 5 – Calculus

Learn all about calculus in this chapter: from learning about average gradient, to limits, to gradient at a point; before learning how to use first principals to differentiate and then learn the short rules of differentiation. Move on to learning how to draw a cubic graph and solving cubic graph equations for the minimum and […]

## Grade 12 Chapter 4 – Factorisation, The Factor theorem and Inequalities

Practice your basic factorisation skills then move on to the factor and remainder theorem before learning how to factorise cubic equations. Finally learn how to deal with inequalities with our original questions. Download here: Chapter 4 – Factorisation, The Factor theorem and Inequalities

## Grade 12 Chapter 3 – Functions and Inverses

Revise the straight line, hyperbola and parabola functions and then practice determining whether a given graph is a function and use this in the application of log graphs and exponential graphs. Download here: Chapter 3 – Functions and Inverses

## Grade 12 Chapter 2 – Number Patterns, Sequences and Series

Use this chapter to revise quadratic patterns and practice your skills with the sequences and series sections that cover all the basics, sum to infinity and sigma notation. Remember to try all the questions because the more you practice the better you get. Download here: Chapter 2 – Number Patterns, Sequences and Series

## Grade 12 Chapter 1 – Logarithms and Logarithm Applications

In this chapter you can revise your exponential skills as well as your surd skills (because logs are linked to exponents) and then move onto practicing the basics of logs and finally move onto practicing applications of logs with regards to finance.
