### Plan for 26th April

• Functions Notes and Qns
• Sets
• Function basics: definition, domain and range
• Inverse functions
• Existence
• Domain and range
• Formula
• Relationship between $f$ and $f^{-1}$
• Composite functions
• Existence
• Domain and range
• Formula
• $f^2(x), f^3(x), ff^{-1}, f^{-1}f$

### Plan for 11th April

• Curve Sketching Companion Questions
• GC techniques
• Asymptotes and rational functions (fractions)
• Common follow up techniques: from graph, discriminant
• To practice on discriminant:
• Parametric equations: curve sketching, changing to cartesian
• Conics: curve sketching, asymptotes, completing the square

### Summary notes

• These are the summary notes for the pure math section of our syllabus: Notes – Elements of H2 A Level Math
• A brief summary of our current topic is one page 3 under the two boxes “Asymptotes” (Top left) and “Conics” (Top right)
• The discussion on parametric equations is summarized in page 5 under “Parametric equations” (the only relevant point at the moment is to remember to change “tMin” and “tMax” in the “window” screen

### HW plan

• School tutorial
