Math ni kila mahali, hata katika maeneo ambayo hatuwezi kutambua mara moja. Kwa mfano, mahusiano ya hisabati yanaelezea uhamisho wa picha, mwanga, na sauti. graph sinusoidal katika Kielelezo\(\PageIndex{1}\) mifano muziki kucheza kwenye simu, redio, au kompyuta. Grafu hizo zinaelezwa kwa kutumia equations trigonometric na kazi. Katika sura hii, sisi kujadili jinsi ya kuendesha equations trigonometric algebraically kwa kutumia formula mbalimbali na utambulisho trigonometric. Pia tutachunguza baadhi ya njia ambazo equations ya trigonometric hutumiwa kutengeneza matukio halisi ya maisha.
Kielelezo\(\PageIndex{1}\): sine wimbi mifano usumbufu. (mikopo: mabadiliko ya kazi na Mikael Altemark, Flickr).
