1 CHAPTER 3 PLANE AND SPHERICAL TRIGONOMETRY 3.1 Introduction It is assumed in this chapter that readers are familiar with the usual elementary formulas encountered in introductory trigonometry. We start the chapter with a brief review of the solution of a plane triangle. While most of this will be familiar to readers‚ it is suggested that it be not skipped over entirely‚ because the examples in it contain some cautionary notes concerning hidden pitfalls. This is followed by a quick review of spherical

any challenges that I face‚ like Honors Trigonometry. Math has been my best subject throughout school. However‚ in my first semester of Honors Trigonometry‚ I was repeatedly getting C’s on tests‚ which resulted in me earning a B first semester. When I considered dropping the class‚ I recalled what I had to do to get my axel back. Keeping that in mind‚ I decided to stick it through in Honors Trigonometry. I directed more of my time and energy on Trigonometry homework and studied harder throughout the

Right Triangle Trigonometry Trigonometry is a branch of mathematics involving the study of triangles‚ and has applications in fields such as engineering‚ surveying‚ navigation‚ optics‚ and electronics. Also the ability to use and manipulate trigonometric functions is necessary in other branches of mathematics‚ including calculus‚ vectors and complex numbers. Right-angled Triangles In a right-angled triangle the three sides are given special names. The side opposite the right angle is called the

To start the experiment‚ weigh the mass of the cart with the picket fence and record the mass on an excel worksheet. The combined weight of the cart and the picket fence will be referred to as M. After weighing the cart with the picket fence‚ assemble the dynamic track by installing the photogate at an appropriate position. Additionally‚ install the pulley at the applicable end of the dynamic track. Next‚ hook up the inextensible string to the end of the cart. The attached string should be facing

Pythagorean Theorem: Some False Proofs Even smart people make mistakes. Some mistakes are getting published and thus live for posterity to learn from. I ’ll list below some fallacious proofs of the Pythagorean theorem that I came across. Some times the errors are subtle and involve circular reasoning or fact misinterpretation. On occasion‚ a glaring error is committed in logic and leaves one wondering how it could have avoided being noticed by the authors and editors. Proof 1 One such error appears
