Lesson 5. The Intricacies of Polynomials and Rational Functions

Polynomials are fundamental in calculus, representing expressions with constant coefficients and variable powers, whereas rational functions focus on polynomial-based fractions acknowledging domain limitations. The domain, roots, and intercepts of these functions help in graphing and solving them, with tools like the quadratic formula applied for quadratic functions.

Lesson 6. Roots and Asymptotes: Uncovering Mathematical Patterns

Synthetic division offers a streamlined method to determine the roots of higher-degree polynomials, shedding light on their underlying structure and factors. Rational functions' asymptotic behavior, whether approaching infinity or shifting diagonally, is critical to understanding their limits and domain.

Polar coordinates offer an alternative to the traditional Euclidean system, simplifying various mathematical problems by expressing a point's location as a distance and an angle from the origin. This lesson covers the relationship between polar and rectangular coordinates, conversion techniques, and the benefits of using polar coordinates in certain algebraic expressions.

Lesson 14. Circles and Parabolas: A First Look

Conic sections are derived from slicing a cone at various angles, resulting in shapes like circles and parabolas, which are explored in this lesson. The algebraic and graphical properties of these shapes demonstrate their underlying mathematical principles while highlighting their unique characteristics.

Lesson 15. Exploring the Intricacies of Ellipses and Hyperbolas

Ellipses, described as flattened circles, accommodate the Sun in their focus, portraying celestial orbits, while hyperbolas, akin to parabolas, demonstrate more open loops. Conic sections dictate planetary paths, emphasizing varying speeds and distances that result in hyperbolic or elliptical motions.

Lesson 16. Limits: The Gateway to Calculus

Limits enable us to predict how functions behave near specific points, playing a critical role in calculus concepts like differentiation and integration. By examining both one-sided and two-sided limits, we delve into the nuances of function behavior and their continuity.

Lesson 17. Diving into Sequences and Series

Exploring sequences and series, the lesson offers a holistic overview of these comprehensive topics, detailing how sequences are ordered number sets, while series unite sequence terms into sums. Essential concepts like convergence and divergence provide a sneak peek into the world of limits, paving the way for calculus applications.
