Basic Trigonometry, Significant Figures, and Rounding — A Quick Review is a zero credit course intended for those who might find themselves a bit rusty and would like a quick refresher. The information in the course is useful for application to the solution of structural problems especially in the fields of statics and strength of materials.
The trigonometry review includes demonstrating - through the use of several example problems — the use of the basic trigonometric functions including: the sine, cosine and tangent and their inverse; the Pythagorean Theorem; the Sum of the Angles; the Law of Sines; and the Law of Cosines. The significant figures and rounding review includes a discussion of the precision and validity of an answer, along with rules and guidelines for using the appropriate number of significant figures, and for rounding answers appropriately.
This is a FREE, non-credit course with no test. Enjoy.
