HISTORICAL CONTRIBUTION C3 Applications of Calculus is the biggest topic in the Advanced course, contributing a massive 18% to past Mathematics exams, on average over the past decade. This topic has been split into five sub-topics for analysis purposes: 1-The Derivative Function and its Graph (3.2%), 2-Curve Sketching (5.5%), 3-Tangents (1.4%), 4-Maxima and Minima (6.1%) and 5-Rates of Change (1.8%). This analysis looks at The Derivative Function and its Graph. HSC ANALYSIS - What toexpect and commonpitfalls The Derivative Function and its Graph is a challenging sub-topic that demands a solid conceptual understanding of the first and second derivative. Students are regularly asked to explore the graphical relationship between f(x) and f ´(x). This area has caused problems in the past and deserves attention. This sub-topic has been tested in seven exams over the past decade (notably absent in 2019) and has produced sub-50% mean marks on a majority of occasions. A revision focus is recommended.
