Lithini igama lesiJamani leTrigonometry?

Bafundi abathandekayo, namhlanje ndiza kuchaza ukulingana kweJamani kunye nokusetyenziswa kwengqiqo yetrigonometry ngokubanzi. I-Trigonometry ichazwa njenge "Trigonometrie" ngesiJamani. Eli gama livela kwimvelaphi yesiGrike kwaye lithatyathwe kwigama elithi "trigonon" (unxantathu) kunye ne "metron" (umlinganiselo). Ngamanye amazwi, itrigonometry ithetha umlinganiselo novavanyo loonxantathu.

I-Trigonometry lisebe elibalulekileyo lejometri kwaye ihlola ubudlelwane phakathi kwee-engile, amacala kunye nonxantathu. I-Trigonometry isetyenziswa rhoqo kwiinkalo ezininzi, kuquka ubunjineli, i-physics, kunye ne-astronomy. Umzekelo, imisebenzi yetrigonometric isetyenziselwa ukulinganisa ubude besakhiwo, ukujonga indawo yenqanawa, okanye ukubala i-orbit yeplanethi.

IiNgcebiso eziSisiseko zeTrigonometry

Amagama asisiseko asetyenziswa rhoqo kwitrigonometry ngala:

1. I-Winkel (i-Angle): Ii-angles zidlala indima ebaluleke kakhulu kwi-trigonometry. Ii-engile zidla ngokubonakaliswa ngokwezidanga (Grad) okanye iiradians (Radiant).

2. I-Seite (Icala): Unxantathu unamacala amathathu: i-Hypotenuse (icala lasekunene), i-Kathete (icala lasekunene) kunye ne-Gegenkathete (icala elichaseneyo).

3. I-Sinus (Isono), i-Cosinus (i-Cos) kunye ne-Tangens (i-Tan): Imisebenzi ye-Trigonometric ebonisa ubudlelwane phakathi kwe-angle kunye necala.

4. I-Dreieck (unxantathu): Oonxantathu ziibhloko zokwakha ezisisiseko kwitrigonometry. Ubudlelwane phakathi kwee-engile kunye namacala oonxantathu buyahlolwa.

ITrigonometry yesiJamani iSampuli yezivakalisi

Masenze umzekelo wengqikelelo yetrigonometry ngokuyisebenzisa kwizivakalisi zesiJamani:

– Injineli ibala ubude besakhiwo ngoncedo lwetrigonometry.

-Kwisifundo sefiziksi, unjingalwazi uchaze ukusetyenziswa kwetrigonometry kusetyenziso olungcono lwemisebenzi. (Kwiklasi yefiziksi, unjingalwazi wachaza ngokusetyenziswa kwetrigonometry ekumiseleni imigama.)

– Ukwakhiwa kweebhulorho, iinjineli kufuneka zenze izibalo zetrigonometric.

– Die Studenten lernten im Mathematikunterricht die Grundlagen der Trigonometrie kennen. (Abafundi bafunde iziseko zetrigonometry kwiklasi yezibalo.)

Njengoko kunokubonwa, ingcinga yetrigonometry ngesiJamani isetyenziswa rhoqo kwimimandla efana nobunjineli, ifiziksi, kunye nenzululwazi ngeenkwenkwezi. Iikhonsepthi ezisisiseko ezinjengoonxantathu, ii-engile, kunye nemisebenzi yetrigonometric nazo zicaciswa ngesiJamani ngamagama athi “Winkel”, “Seite”, “Sinus”, “Cosinus”, “Tangens”, kunye no-“Dreieck”.
