Trigonometry Learning Aid

thingiverse

This is a learning aid for trigonometry. It is a trigonometric mnemonic chart, which is a fancy way of saying it is a chart that will help you remember trig identities, and four handouts for students to look at and complete. How I Designed This This was designed in 123D Design. Project: Trigonometry Learning Aid Project Name Trigonometry Learning Aid. Overview & Background This chart will help students remember all the trigonometric identities. Objective Students should be able to recall all trig identities fairly easily. Audiences This is for anyone studying trigonometry. Subject Math. Specifically, trigonometry. Skills learned Trigonometry. Lesson/Activity Students should look at the chart, memorize the mnemonics, and then complete the handouts. The handouts are included as PDF files. They should be completed in order. o To construct the chart, use this sentence: One single pale cosplayer, sleeping on a cot, can’t seem to catch what he’s seeking: tan-lines. o Then write out the identities using these methods and mnemonics (to remember operation): o center out to opposing sides, “center over and out”, example: 1/sin x = csc x; o small triangles, staring at the top left and going clockwise, “adding square triangles”, ex: sin^2 x + cos^2 x = 1; o two neighbors along the edge, “two timing neighbors”, ex: sin x = cos x * tan x; o one corner and go clockwise, “overclocking”, ex: sin x = cos x / cot x; o one corner and go counter-clockwise/anti-clockwise, “overclocking” (or “over-anti-clocking”, if you like), ex: sin x = tan x / sec x. Duration 30 minutes Preparation Basic trig knowledge. Pencil or pen and the handouts. References More information can be found at Wikipedia: Mnemonics in trigonometry This comic by The Pigeon Gazette will help consolidate the mnemonic of a pale cosplayer at the beach. Rubric & Assessment Students should have four handouts, three of which they had to complete on their own. They should be able to recreate the chart and list of identities without looking at the 3D printed chart or the handouts. Handouts & Assets Handouts are included as PDFs. JPG previews are provided below. 1) All mnemonics and chart and formulas. 2) mnemonics and chart, with empty space for students to write formulas. 3) mnemonic to construct chart with space to draw chart and write other mnemonics and formulas. 4) space to draw chart, write mnemonics and formulas.
