Cishe nje sine eziyinkimbinkimbi futhi cosine

Cishe nje sine eziyinkimbinkimbi futhi cosine!

Abafundi abaningi nomqondo sine, cosine, tangent, cotangent kubonakale eziyinkimbinkimbi, kodwa empeleni zilula. Udinga nje ngeso lengqondo okunye kwalokhu imiqondo uyiqonde ngokucacile bona.

Ngenxa yalesi sipho isitoko izinto ngakwesokunene, ezifana izibaya, amapensela, stapler, highlighter, irabha, njll .. Futhi isiqiniseko wokulinganisa isikali wenze ukuboniswa. Konke kuyoba lula kunalokho ucabanga!

Ingabe ukuqoqa izinto kusuka yethu unxantathu kwesokudla yomumo emaceleni A, B, C, engela Y.

unxantathu Neutral uthi cha lutho emangalisayo, njengoba kunoma yiliphi ebhukwinitifundvo. Kodwa namanje ubekezele futhi sizoqhubeka. Thatha umbusi futhi ukukala ohlangothini B, kufanele ukuthi kwenzeke kanjani ukuba into, uthi ipensela. Kala ubude ipenseli ezaziwazungezile umphumela etholwe izilinganiso ngamasentimitha. uhlangothi Zethu B ake ukuba amasentimitha amathathu. Ulinganiseke ohlangothini A. ngamasentimitha amahlanu. Manje uhlukanise ubude eceleni A ukumelela B. Lokhu ubude isilinganiso ukuya ku B = A / B = 5/3, ingahlukaniswa ukuze A B ukuthola 3/5, C B, njll

Futhi manje ukwandisa unxantathu. Nweba isandla A, B no-C Kwenze ngokusebenzisa zokubhala yayo izinto.

Manje ezinhlangothini unxantathu A, B, C jikisa D, G, L. Kala izinhlangothi A no F, isimo sabo sengqondo 10/6. Futhi ngakho-A / F = 10/6 = 5/3. Ubuhlobo nezinye izinhlangano ezifanele futhi akukashintshi. Ungakwazi ukukala ubude, futhi ungakukholelwa lokhu. Lena ibhizinisi wonke umuntu! Can ezinqumela ukushintsha ubude emaceleni e ilungelo unxantathu, khuphula, nciphisa, ngaphandle kokushintsha engela Y - ubuhlobo abathintekayo musa ukushintsha.

Uma engela ushintsho Y, ukwandisa noma ukunciphisa ke, zonke ohlangothini ubude ubudlelwano ukushintsha. Ungazibonela ngokwakho.

Njengoba ayethembisile ngaphambili, yonke into ilula. Ake sifika eziphethweni ezithile. Ubudlelwano ku unxande unxantathu izinhlangothi akuxhomekile ubude izinhlangothi (zibheke ohlangothini olufanayo), kodwa sithembele ngokuqinile kule engela. Futhi zonke lezi ubudlelwane we amaqembu Yiqiniso zinamagama:

ISONO Y = A / C Sine ye-engeli Y iyona ratio ophikisayo (ayengayicabangi ekhoneni) kuya hypotenuse.

COS Y = B / C Lokhu engela Y cosine ohlangothini eduze isilinganiso (ongaphakeme) kuya hypotenuse.

Sine futhi cosine kuyinto imisebenzi Trigonometric, futhi kokuqonda ezinye izinombolo ahlukile engela ngayinye. Kwabe sekuvela ukuthi konke silula.

Sine futhi cosine yiwona ngqo imisebenzi Trigonometric. Esuselwe zingabantu imisebenzi Trigonometric ezifana tangent (TG x) kanye cotangent (ctg x).

Okunye imisebenzi Trigonometric secant (isekhondi x) kanye CSC (cosec x), kodwa kungenzeka ngeke ukuhlangabezana kaningi. Ngaphezu kwalezi eziyisithupha, kukhona eminye kuyaqabukela esetshenziswa imisebenzi Trigonometric (versinus njll), futhi umsebenzi Trigonometric (sine arc, arc cosine futhi t. D.).

Ngithemba wena zonke ukuqonda, futhi bakwazi ukusebenzisa!
