2010 Meridian Junior College (MJC) H2 Mathematics Preliminary Examination

• 9740 had PGFs (Probability Generating Functions). 9758 removed it.
• 9740 had DEs using integrating factor. 9758 emphasizes systems & transforms.

• Differentiation: The paper included a question involving related rates or parametric differentiation. The algebra was slightly tedious, causing careless mistakes.
• Integration: This was the highlight of Paper 1.
  2. The complex numbers $z_1 = 2 + 3i$ and $z_2 = 1 - 2i$ are given.
