The kuphunzira za trigonometry kumakhudza kuphunzira Bwanji trigonometric ntchito - monga sine kapena cosine wa ngodya, mwachitsanzo - akhoza kugwiritsidwa ntchito pozindikira makona ndi makulidwe a mawonekedwe enaake. Ayeneranso kugwiritsa ntchito ntchitoyi kuti athandize ophunzira kukulitsa luso lawo.

Ndiye, chifukwa chiyani trigonometry imagwiritsidwa ntchito pamakona atatu oyenera?

Trigonometry imagwiritsidwa ntchito mu chilichonse kulondola angled makona atatu chifukwa ife tikudziwa izo makona atatu angle sum ndi 180 ndipo ngati ilipo kulondola ngodya makona atatu Kuposa ngodya inayo ndi yocheperapo 90 ndipo idzabwera muchigawo choyamba pamene machimo onse, cos ndi tan ali abwino koma pamene tipita patsogolo pa 2 quadrant cos ndi tan ndi negative komanso mu

Komanso Dziwani, chifukwa chiyani trigonometry iyenera kusungidwa mu maphunziro? Trigonometry amagwiritsidwa ntchito m'ntchito zambiri kuphatikizapo kufufuza, uinjiniya, zamankhwala, ndi zakuthambo. Trigonometry iyenera kukhala kusungidwa mu maphunziro chifukwa ndi imodzi mwamaphunziro omwe amagwiritsidwa ntchito kwambiri masamu ndipo ndiyofunikanso kuti timvetsetse maphunziro omwe amaphunzitsidwa m'masamu apamwamba.

Chifukwa chake, kafukufuku wa trigonometry ndi chiyani?

Trigonometry (kuchokera ku Greek trigonon, "triangle" ndi metron, "measure") ndi nthambi ya masamu yomwe maphunziro mgwirizano pakati pa utali wam'mbali ndi makona a makona atatu. Mundawu udawonekera m'dziko lachi Greek m'zaka za zana la 3 BC kuchokera pakugwiritsa ntchito ma geometry kupita ku zakuthambo. maphunziro.

Kodi Basic trigonometry ndi chiyani?

Trigonometry, nthambi ya masamu yokhudzana ndi ntchito zenizeni za ngodya ndikugwiritsa ntchito kuwerengera. Pali ntchito zisanu ndi imodzi za ngodya zomwe zimagwiritsidwa ntchito kwambiri trigonometry. Mayina awo ndi chidule chake ndi sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), ndi cosecant (csc).
