In this post, we solve optimisation problems from a wide variety of fields using first and second derivatives. This syllabus dot point is a part of the QCE Maths Methods course under the topic Further Differentiation and Applications 3 and sub-part The Second Derivative and Applications of Differentiation, specifically focusing on optimisation problems.
Part 1: Setting up equations
Part 2: Using the derivative to find possible turning points
Part 3: Finding the hidden conditions
Part 4: Optimisation examples
