Precalculus: An Investigation of Functions is a free, open textbook covering a two-quarter pre-calculus sequence including trigonometry. The first portion of the book is an investigation of functions, exploring the graphical behavior of, interpretation of, and solutions to problems involving linear, polynomial, rational, exponential, and logarithmic functions. An emphasis is placed on modeling and interpretation, as well as the important characteristics needed in calculus. The second portion of the book introduces trigonometry. Trig is introduced through an integrated circle/triangle approach. Identities are introduced in the first chapter, and revisited throughout. Likewise, solving is introduced in the second chapter and revisited more extensively in the third chapter. As with the first part of the book, an emphasis is placed on motivating the concepts and on modeling and interpretation. In addition to the paper homework sets, algorithmetically generated online homework is available as part of a complete course shell package, which also includes a sample syllabus, teacher notes with lecture examples, sample quizzes and exams, printable classwork sheets and handouts, and chapter review problems. If you teach in Washington State, you can find the course shell in the WAMAP.org template course list. For those located elsewhere, you can access the course shell at MyOpenMath.com. A self-study version of the online course exercises is also available on MyOpenMath.com for students wanting to learn the material on their own, or who need a refresher.
Precalculus: Uchunguzi wa Functions ni bure, wazi kitabu cha masomo kufunika mbili-quarter precalculus mfululizo ikiwa ni pamoja na trigonometry. Sehemu ya kwanza ya kitabu ni uchunguzi wa kazi, kuchunguza tabia ya graphic ya, tafsiri ya, na ufumbuzi wa matatizo yanayohusisha linear, polynomial, rational, exponential, na logarithmic kazi. Mkazo ni kuwekwa juu ya modeling na tafsiri, kama vile sifa muhimu zinahitajika katika calculus. Sehemu ya pili ya kitabu hicho inaonyesha trigonometry. Trig ni kuletwa kupitia mzunguko jumuishi / pembetatu mbinu. Utambulisho ni kuletwa katika sura ya kwanza, na revisited katika wote. Vivyo hivyo, kutatua ni kuletwa katika sura ya pili na revisited zaidi kwa kina katika sura ya tatu. Kama ilivyo na sehemu ya kwanza ya kitabu, msisitizo ni kuwekwa juu ya kuhamasisha dhana na juu ya modeling na tafsiri. Pamoja na seti za kazi za nyumbani za karatasi, kazi za nyumbani za mtandaoni zinazozalishwa kwa algorithm zinapatikana kama sehemu ya kifurushi kamili cha kozi, ambayo pia inajumuisha mtaala wa sampuli, maelezo ya mwalimu na mifano ya hotuba, sampuli za mtihani na mtihani, karatasi za kazi za darasa zinazoweza kuchapishwa na handouts, na matatizo ya ukaguzi wa sura. Ikiwa unafundisha katika Jimbo la Washington, unaweza kupata shell ya kozi katika orodha ya kozi ya template ya WAMAP.org. Kwa wale ziko mahali pengine, unaweza kupata kozi shell katika MyOpenMath.com. Toleo la kujifunza la mazoezi ya kozi ya mtandaoni pia inapatikana kwenye MyOpenMath.com kwa wanafunzi wanaotaka kujifunza nyenzo peke yao, au ambao wanahitaji kurekebisha.
