Mathematical Foundations II is the second course in a sequence specially crafted for adults seeking the most direct path to prepare for university math courses. Building on the basic algebra covered in Mathematical Foundations I, students in Mathematical Foundations II generalize their understanding of algebra to more advanced functions (including trigonometry) and become acquainted with limits and derivatives in calculus. Upon completing the course, students will be prepared for Mathematical Foundations III, the final stepping stone in preparing for university-level math.

Master the algebra of advanced functions including quadratics, logarithms, and trigonometry. Dive deep into the theory of polynomials, learn the basics of limits, derivatives, and integrals from calculus, and explore a variety of concepts from higher math including complex numbers, vectors, probability, and statistics.

- Understand the relationship between logarithms and exponents and use this understanding to evaluate logarithms.

- Apply trigonometric functions to solve for unknown sides and angles in right triangles.
- Leverage the unit circle as a conceptual framework for evaluating special trigonometric ratios.
- Graph and describe properties of trigonometric functions by relating them to the unit circle.
- Use the law of sines and the law of cosines to solve for unknown angles and sides in general triangles.

- Leverage factoring and the quadratic formula as complementary techniques for solving quadratic equations and graphing quadratic functions.
- Extend previous knowledge of algebraic techniques to solve nonlinear equations involving polynomials, radicals, exponents, and logarithms.
- Understand how transformations affect the shape of a function's graph and use this understanding to graph transformed quadratic, absolute value, exponential, radical, logarithmic, and trigonometric functions.

- Understand the relationship between zeros and factors of polynomials.
- Divide polynomials using synthetic and long division.
- Understand the relationship between the value of a polynomial at a given input and the remainder obtained when dividing the polynomial by the corresponding binomial.
