1.Continuing with differentiation, we continued with more Maxima/Minima questions as well as Rates of Change. We looked at some higher order application questions which challenged our geometry skills, among others. Let's note that mensuration formulae are essential, and look out for similar triangles! Also, don't forget your trigo skills. This is a chapter you've trained all your Math life for :) Also, we did an express bit of Inequalities revision, covering four core question types. Do followup with the practice questions, which includes some System of Linear Equations questions too.
