Unit Overview: The primary focus of this unit is the understanding of functions. Students begin with exploring linear functions and their graphs. They use scatter plots and graphing technology to find linear models for sets of data. Quadratic, polynomial, and rational functions are analyzed, sketched, graphed, and solved. Graphing technology is used to find quadratic models for data. Students extend their knowledge to recognize, evaluate, and graph exponential and logarithmic functions. Properties of logarithms are used to evaluate, rewrite, expand, or condense logarithmic expressions. Exponential growth and decay models are used to solve real-life problems. Students will also explore the concepts of data and curve fitting.

Enduring Understandings What “big ideas” are the focus? What are the “essential questions?”

Functions are widely used to model phenomena in the physical world. Polynomial Functions can be used to model many different types of real world situations in which data changes from increasing to decreasing or from decreasing to increasing more than once. Rational functions are used to model situations involving two variables in which they vary inversely. Exponential and logarithmic functions are valuable when studying and predicting information relating to growth and decay.

Unit Overview:

In this unit, students will be introduced to trigonometry. At first, they will convert between degree and radian measures, find arc lengths and areas of sectors of circles, and investigate, evaluate, and graph the six trigonometric functions and the inverse trigonometric functions. They will then solve trigonometric equations and apply them to problems from analytic geometry. They will explore changes in the sine and cosine curves and use these changes to develop models of real-world periodic phenomena. They will also prove a variety of trigonometric identities and use them to simplify and solve more difficult trigonometric expressions and equations. Ultimately, they will use trigonometry to find the unknown sides or angles of a triangle, develop a formula to find the area of a triangle in terms of the sine of one of the angles, and use the law of sines and the law of cosines to solve problems from navigation and surveying.

Enduring Understandings An angle is represented as a rotation about a point and is measured in degrees or radians.

Assessments to be Used to Address Student Understanding How will you assess the students’ ability to know/do the big ideas in a meaningful way?

The sine and cosine functions are defined in terms of the coordinates of a point on a circle.

Summative/Formative

The definitions of the other trig functions involve restrictions on either the x or y coordinate of a point on the terminal ray of an angle.

Projects

Trig functions are periodic and can experience transformations. An identity is true for all values of the variable for which the statement is meaningful. The Law of Sines and the Law of Cosines can be used to find the lengths of sides and the measures of angles in a triangle. In surveying applications, the angles’ measures are east or west of the north-south line. In navigation applications, the bearing of the ship or airplane is measured clockwise from the northsouth line.

Unit Overview: This unit begins with an exploration of conic sections. The equations for conic sections are derived from the definition of conic sections and from the distance formula. Students then use rectangular equations to graph the conic sections. The terms and sums of sequences are written, and students learn to recognize, write, and use arithmetic and geometric sequences. Mathematical induction is used to prove statements involving a positive integer n. The Binomial Theorem and Pascal’s Triangle are used to calculate binomial coefficients and write binomial expansions. Counting problems are solved using the Fundamental Counting Principle, permutations, and combinations. The unit concludes by finding the probabilities of events and their complements.

Enduring Understandings What “big ideas” are the focus? What are the “essential questions?”

Conic sections can be applied to real world applications (i.e. navigation, astronomy, communications). Sequences and Series can be described in terms of arithmetic and geometric types. They are useful in modeling sets of values in order to identify a pattern.

n/a Unit Overview: The main focus of this unit is to give students a first look at concepts of Calculus with the topic of limits. Students use the definition and properties of limits and direct substitution to evaluate limits. Students are given an in-depth look at the techniques used for evaluating limits. Tangent lines, limits at infinity, and sequences conclude this unit of study.
