這是一門半學期的課，主題是限制條件下的最佳化問題，目的是裝備學生用微積分工具探討重要的經濟學議題。 課程前三周簡介處理最佳化問題所需的線性代數工具；內容包含矩陣的秩、行列式、特徵值與特徵向量，和對稱矩陣的正負定性。 最佳化問題討論在等式限制條件，不等式限制條件，與混和限制條件下求目標函數極值的解法。同時我們還介紹Kuhn-Tucker陳述式，說明 Lagrange 乘子的意義(影子價格)，推導包絡定理，並講解限制條件下的二階微分測試，以判斷臨界點是局部極大或極小值。 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；同時會示範最佳化問題在經濟學的應用，幫助學生將微積分與專業科目結合。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。 The goal of this course is to employ tools from Calculus and develop mathematical theory to tackle important problems, specifically constrained optimization problems, in Economics. We shall begin with a crash course in linear algebra. We will define the rank, determinant, eigenvalues, eigenvectors, and definiteness of matrices. These concepts will be used to solve optimization problems with equality or inequality constraints (or a mix of both). Then we proceed to discuss the Kuhn-Tucker formulation, the economic interpretation of Lagrange multipliers as shadow prices, the envelope theorem and the second order test under constraints which determine the nature of a critical point.   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 optimization problems in Economics are illustrated in order to promote a more organic interaction between the theory of Calculus and students' own fields of study. This course also provides discussion sessions in which students are able to make their skills in handling calculations in Calculus more proficient under the guidance of our teaching assistants.

熟練微積分技巧，並能應用微積分理解並推導重要的經濟理論。 Students would be familiar with Calculus as a tool and be able to apply it to derive important economic theories.

需有「微積分1」「微積分2」「微積分3」的預備知識。 認真參與課堂和習題課的活動與討論。 Students participating in the course should have taken Calculus 1, 2, and 3. They are expected to attend and participate actively in lectures as well as discussion sessions.
