6.0 變分 (Variations)

變分 (Variations) 亦稱為“變數法”。

  • 簡單嚟講“變分”就係講“兩個(或以上)變數之間嘅關係”。

喺文憑課程入面要識嘅“變分”有四種:

  • 正變 (Direct variation)
  • 反變
  • 聯變
  • 部分變

而大家要學嘅包括:

  • 理解正變和反變及其在解現實生活問題時的應用(Understand Direct Variations and Inverse Variations, and their Applications to Solving Real-Life Problems)
  • 理解正變和反變的圖像(Understand the Graphs of Direct Variations and Inverse Variations)
  • 理解聯變和部分變及其在解現實生活問題時的應用(Understand Joint Variations and Partial Variations, and their Applications to Solving Real-Life Problems)
