### Course Outline

Pre-calculus 12 is an advanced high school mathematics course. Students will explore the following topics:

- Trigonometry
- Relations and Functions:
- Permutations, Combinations, and Binomial Theorem

#### Trigonometry (T):

Students will be expected to develop trigonometric reasoning.

- Solve problems, using the six trigonometric ratios for angles expressed in radians and degrees.
- Graph and analyze the trigonometric functions sine, cosine, and tangent to solve problems.
- Solve, algebraically and graphically, first- and second-degree trigonometric equations with the domain expressed in degrees and radians.
- Prove trigonometric identities, using:

- reciprocal identities,

- quotient identities,

- Pythagorean identities,

- sum or difference identities (restricted to sine, cosine, and tangent),

- double-angle identities (restricted to sine, cosine, and tangent)

#### Relations and Functions (RF):

Students will be expected to develop algebraic and graphical reasoning through the study of relations.

- Demonstrate an understanding of operations on, and compositions of, functions.
- Understand the effects of horizontal and vertical translations on the graphs of functions and their related equations.
- The effects of horizontal and vertical stretches on the graphs of functions and their related equations.
- Apply translations and stretches to the graphs and equations of functions.
- Understand the effects of reflections on the graphs of functions and their related equations, including reflections in the x-axis, y-axis, and line y = x.
- Understand inverses of relations.
- Demonstrate an understanding of logarithms.
- Demonstrate an understanding of the product, quotient, and power laws of logarithms.
- Graph and analyze exponential and logarithmic functions.
- Solve problems that involve exponential and logarithmic equations.
- Understand factoring polynomials of degree greater than 2 (limited to polynomials of degree ≤ 5 with integral coefficients).
- Graph and analyze polynomial functions (limited to polynomial functions of degree ≤ 5 ).
- Graph and analyze radical functions (limited to functions involving one radical).
- Graph and analyze rational functions (limited to numerators and denominators that are monomials, binomials, or trinomials).

#### Permutations, Combinations, and Binomial Theorem (PCB):

Students will be expected to develop algebraic and numeric reasoning that involves combinatorics.

- Apply the fundamental counting principle to solve problems.
- Determine the number of permutations of n elements taken r at a time to solve problems.
- Determine the number of combinations of n different elements taken r at a time to solve problems.
- Expand powers of a binomial in a variety of ways, including using the binomial theorem (restricted to exponents that are natural numbers).
