這是一門半學期的課程，主要介紹單變數函數的微分運算，和微分在各領域豐富的應用。內容涵蓋極限與連續的定義，微分技巧，畫函數圖形，和極值問題等。課堂上將講解定義並推導重要定理，以培養學生邏輯推理與分析能力；同時會示範微積分在各領域的應用，幫助學生將微積分與其他專業科目結合。本課程還設有習題課，學生將在助教的帶領下熟練微積分的計算並完成學習單。
Differentiation on functions of a single variable together with its profound applications in various subject areas are introduced in this half-semester course. In particular, this course includes the definitions of limits and continuity, techniques of differentiation, curve sketching, strategies for solving extreme-value problems and more.
Definitions are discussed and the most important theorems are derived in the lectures with a view to help students to develop their abilities in logical deduction and analysis. Practical applications of Calculus in various fields are illustrated in order to promote a more organic interaction between the theory of Calculus and students' fields of study. This course also provides discussion sessions in which students are able to improve their skills in
handling calculations in Calculus and complete small projects under the guidance of our teaching assistants.
