The focus and themes of the Introduction to Calculus course address the most important foundations for applications of mathematics in science, engineering and commerce. The course emphasises the key ideas and historical motivation for calculus, while at the same time striking a balance between theory and application, leading to a mastery of key threshold concepts in foundational mathematics. Students taking Introduction to Calculus will: \tgain familiarity with key ideas of precalculus, including the manipulation of equations and elementary functions (first two weeks), \tdevelop fluency with the preliminary methodology of tangents and limits, and the definition of a derivative (third week), \tdevelop and practice methods of differential calculus with applications (fourth week), \tdevelop and practice methods of the integral calculus (fifth week).
