Pre-Calculus 11 prepares learners for the world of calculus. Learners will build on skills from Math 10 and further explore: quadratic functions, equations, trigonometry, rational and radical numbers, and arithmetic and geometric sequences and series. Why is calculus important, you ask? Calculus has a multitude of real-life applications. Included among the disciplines that use calculus are physics, engineering, economics, statistics, and medicine with physical concepts such as heat, light, electricity, and motion all informed by the concepts underpinning calculus.
