Chapt. 3 Vectors and Trigonometry 27 003 qmult 00302 1 1 2 easy memory: trig abbreviation Extra keywords: too simple-minded even for tests 14. Trigonometry is often abbreviated to a) triggy. b) trig. c) gono. d) metro. e) monstro. 003 qmult 00310 1 4 5 easy deducto-memory: transcendental functions 15. “Let’s play Jeopardy ! For $100, the answer is: They are functions that cannot be exactly evaluated by a finite sequence of the algebraic operations of addition, multiplication, and root taking. Examples are the trigonometric, logarithm, and exponential functions.” What are the functions, Alex? 003 qmult 00320 1 4 4 easy deducto-memory: trigonometric functions Extra keywords: mathematical physics 16. “Let’s play Jeopardy ! For $100, the answer is: They are functions whose argument is an angle and which yield the ratios of sides of a right triangle (or right-angled triangle). The functions are extended so that the argument angle can be any value (i.e., greater than 90 and less than 0 ). In these cases, the triangle can be thought of as plotted on the Cartesian plane and as having positive or negative sides depending on quadrant where the hypotenuse vector lies.” What are the functions, Alex?
