Study Notes
Algebra
- Students must solve problems involving simultaneous linear equations and linear inequalities, using a variety of methods, including graphical representations and algebraic approaches.
- Solving quadratic functions is also crucial, specifically through factoring and the quadratic formula.
- The levels of difficulty progress from solving simpler problems (Column "E") to complex problems involving both simultaneous linear equations and inequalities (Column "A").
- Column "A" involves the most demanding skills, requiring students to solve equations and inequalities in 2 variables graphically and algebraically.
Measurement
- Students learn to interpret and utilize logarithmic scales, particularly in representing small and large quantities and changes within different contexts.
- This includes navigating magnitude and scientific notation, utilizing the inverse relationship between exponentials and logarithms.
- Students must apply the Pythagorean theorem and trigonometry to solve practical problems related to right-angled triangles.
- These problems may involve angles of elevation or depression, and bearings.
- Column "A" expects students to apply these concepts and solve complex problems, while Column "E" focuses on a more basic understanding of logarithmic scales.
Probability
- Students must understand and apply conditional probability to solve problems involving compound events.
- This involves using visual tools like tree diagrams and two-way tables to analyze dependent and independent events.
- There is a progression in complexity, with Column "A" requiring students to interpret both dependent and independent events while Column "E" simply focuses on a basic understanding of applying probability.
