Here you'll be introduced to the bare basics of mathematics. Topics include commonly used words and phrases, symbols, and how to follow the order of operations.
An introduction to numerical computation. Emphasis is placed on scientific and engineering notation, the rule of significant figures, and converting between SI and Imperial units.
Trigonometry with Right Triangles
Here we focus on right angle triangles within quadrant I of an x-y plane. None of the angles we evaluate here are greater than 90°. A unit on trigonometry with oblique triangles is covered later.
Trigonometry with Oblique Triangles
This unit is a continuation of trigonometry with right triangles except we'll extend our understanding to deal with angles *greater* than 90°. Resolving and combining vectors will be covered at the end of this unit.
Introduction to Algebra
Functions and Graphs
This unit focuses on analyzing and understand the characteristics of various shapes, both 2D and 3D.
- Identify, measure, and calculate different types of straight lines and angles
- Calculate the interior angles of polygons
- Solve problems involving a variety of different types of triangles
- Calculate the area of a variety of different types of quadrilaterals
- Solve problems involving circles
- Calculate the areas and volumes of different solids
Introduction to Statistics
Definitions and Terminology
In statistics, an entire group of people or things is called a population or universe. A population can be infinite or finite. Examples of finite populations include the number of airplanes owned by an airline, or the potential consumers in a target market. Examples of infinite populations include the number of products manufactured by a company that plans to be in business forever, or the growth of bacteria given ample resources to grow.
A small part of the entire group chosen for study is called a sample. For example, in a study of the heights of students at a particular college, the entire student body is the population. The population is finite because it’s not growing in any way as the study is conducted. Instead of studying every student in the population, we may choose to work with a sample of only 100 students.
Data that has not been organized in any way is called raw data. Data that has been sorted into ascending or descending order are called an array. The range of the data is the difference between the largest and the smallest number in that array.
Question: Arrange the following in ascending order; find its range.
56.2, 72.8, 58.3, 56.9, 67.5
Largest value: 72.8
Smallest value: 56.2
Range: 72.8 – 56.2 = 16.6
Ascending order means smallest to largest: 56.2 → 56.9 → 58.3 → 67.5 → 72.8
