"Demonstrative Geometry" and "Introduction to Trigonometry".
Teaching a Trigonometry course is a daunting task, especially at the collegiate level, since professors have only half the time to cover the material as the teachers in high schools.
When one has to recommend the purchase of books such as Trigonometry for Dummies and Geometry for Dummies (no disparagement of those books is intended] to acquire those skills in the middle of studying college level engineering, I feel that something is terribly wrong with our educational system.
That's why "Sneaky Math: A Graphic Primer with Projects: Ace the Basics of Algebra, Geometry, Trigonometry, and Calculus with Everyday Things" by Cy Tymony is so valuable in that it will show the reader how math is all around us in our daily lives and presents 192 page compendium packed with easy and fun math projects that range from geometry primers; math challenges, tricks and formulas; and algebra primers; to trigonometry primers, calculus primers, and basic fundamentals of numbers and arithmetic.
Maths topped the list as the subject parents struggle with the most, with algebra, fractions and trigonometry least welcomed at home.

The article you reference says the 34:1 slope is the obstacle clearance surface that's evaluated for a three-degree, 20:1 slope, not the three-degree slope itself Last, we dusted off and reviewed some long-neglected high-school trigonometry. For a right triangle with base of 20 and height of one, the angle is arctan(1/20) or 2.86 degrees.
To uproot the misleading concept of negative length or distance from the basic level of trigonometry, realistic definitions of trigonometric ratios have been offered in Bhattacharjee (2012) with the help of vector algebra and they have been subsequently employed to derive the basic formulae of trigonometry in an unambiguous manner.
He was saturated in the amenities of the lower mathematics, and was redolent of old-world trigonometry. He was so highly optimistic and so afraid of depreciating his pupils' capacity that he never believed they could get a sum wrong.
The last few chapters cover related topics such as multivariable functions, trigonometry, probability, Taylor series, and differential equations.
Created by teachers at Uxbridge High School in London and aimed for KS3, KS4 and A level students, the videos explain slowly and clearly some tricky topics such as laws of indices and trigonometry.
This new trigonometry is also introduced by the author and it can be considered as the basis of the new generation of Signal Processing, Electronics and Electrical systems based on variable signals [17].
