• 55 lessons
• 1 quizzes
• 10 week duration
• ##### Numerical Computation

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.

• ##### Measurements

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.

• ##### Geometry

This unit focuses on analyzing and understand the characteristics of various shapes, both 2D and 3D.

### Engineering Notation

Engineering notation is similar to scientific notation, except for a few differences:

• The exponent is a multiple of three (for example, -3, 3, 6, etc.) ; and
• There can be one, two, or three digits to the left of the decimal point, rather than just one digit; to the right of the decimal, it can be as many as required.

Some examples of numbers written in engineering notation are as follows:

Notice how all 4 examples fit the pattern outlined above. Several examples of numbers being converted into engineering notation are demonstrated in the video below:
