**Module 1 – Series and Sequences**

A sequence is an ordered list of numbers. The sum of the terms of a sequence is called a series. While some sequences are simply random values, other sequences have a definite

pattern that is used to arrive at the sequence's terms. Two such sequences are the arithmetic and geometric sequences.

**Module 2 – Trigonometry**

Don’t panic we will help you understand these pesky triangles. Trigonometry is a

branch of mathematics that studies relationships involving lengths and angles of

triangle.

**Module 3A – Quadratics**

Do quadratics feel extraterrestrial to you? Well, fear no more, our approach to

quadratics will leave you feeling well informed and understood. Just bring to it

your equation solving skills, your ability to multiply binomials and a non-linear

way of thinking!

**Module 3B – Quadratics**

In this module we will focus on factoring, completing the square, and the famous

quadratic formula. Don’t get all apprehensive at the word factoring!! Its just

multiplication and addition!

**Module 4 – Radicals**

A "radical" equation is an equation in which at least one variable expression is

stuck inside a radical, usually a square root. “ptffff” That’s it? Oh we will rock radicals just a little square root standing in the way!!

**Module 5 – Rational Expressions and Equations**

Okay let's be rational about this… you get a rational expression when you divide

one polynomial by another. If you have a good understanding of factoring

quadratics, you'll be able to apply this skill here!

**Module 6 – Absolute Values and Reciprocals**

The absolute value of a number may be thought of as its distance from zero. We will introduce you to reciprocal functions, identifying asymptotes, graphs of reciprocal functions, stretching, shrinking, translating, and graphing reciprocal functions.

**Module 7 – Equations and Inequalities**

In this section, you will learn how so solve inequalities. "Solving'' an inequality

means finding all of its solutions. A "solution'' of an inequality is a number which

when substituted for the variable makes the inequality a true statement.
