No data to assess or demonstrates minimal knowledge of learning objective, no mathematical practices used . (RIGHT TRIANGLES). Why do we Need Trigonometry?. In Physics, we will often be using right triangles in diagrams. Trigonometry lets us find missing side lengths and angles of right triangles.. Is it . Introducing Trigonometry. The London Eye (originally called the ‘. Millenium. Wheel’) is a large . F. erris wheel on the South bank of the River Thames.. It is a huge structure which is 120m in diameter.. We have already discussed a few example of trig identities. All identities are meant to serve as examples of equality. Convert one expression into another. Can be used to verify relationships or simplify expressions in terms of a single trig function or similar. Lewis Carroll/Charles Dodgson. Some . fun facts:. .. as a mathematician, Dodgson was, in the words of . . Peter Heath: "An inveterate publisher of trifles [who] was forever putting out pamphlets, papers, broadsheets, and books on mathematical topics [that] earned him no reputation beyond that of a crotchety, if sometimes amusing, controversialist, a compiler of puzzles and curiosities, and a busy yet ineffective reformer on elementary points of computation and instructional method. In the higher reaches of the subject he made no mark at all, and has left none since." . Temiloluwa Adeniyi. Temiloluwa Adeniyi, COFSP Fellow, Pre- Calculus class . Senior , Biomedical Engineering. Gina Rider, COFSP Teacher, Pre- Calculus and Algebra II, Seton High School . RET is funded by the National Science Foundation, grant #EEC . (The Greeks doing trig in fancy dress.). Intro to Trigonometry. For those later influenced by Greek mathematics, trigonometry deals with periodic functions, whose graphs are usually pretty wavy, and whose applications far exceed the polygonal constraints of triangles: periodic motion, sound, and other interesting stuff.. Hopefully, you remember these from last year (you were required to memorize ten of them) plus SOH CAH TOA.. If not, you need to know the reciprocal and quotient identities which are in the blue box on pg A17, and the Pythagorean, Addition, and Double-Angle Formulas which are inside the back cover of your books.. Make sure the calculator is in Degree Mode (DRG button). Practice getting the sine/cos/tan of various angles. Inverse functions:. [. 2. nd. F button. ] .
