Icyitonderwa kuri Inverse ya Tangent
Inyandiko yo guhinduranya tangent ifata uburyo 3 busanzwe: tanโปยน(x), arctan(x), na atan(x).
- tanโปยน(x) Bisanzwe kuri calculatrice yumubiri.
- arctan(x) Ibisanzwe mu mibare isanzwe.
- atan(x) Porogaramu na porogaramu.
Bamwe mubanyeshuri babyita anti tangent kuva ihindura ibyo tangent ikora, nubwo iyi atari imvugo isanzwe.
Kanda buri nyandiko kugirango ugaragaze aho igaragara mu mibare, gahunda, na calculatrice.
tanโปยน(x) ni inyandiko isanzwe kuri calculatrice physique. Superscript -1 yerekana "imikorere ihindagurika," ntabwo "1 / tan (x)".
Kubona tanโปยน yimibare mibi
Tanโปยน yimibare mibi isubiza inguni mbi. Kuberako arctan ubwitonzi nigikorwa kidasanzwe, arctan(-x) = -arctan(x).
- arctan (- 1) = -45 ยฐ cyangwa - ฯ/4 imirasire
- arctan (- โ3) = -60 ยฐ cyangwa - ฯ/3 radians
Tanโปยน ya -1 ni iki?
Tanโปยน ya -1 ni -45 ยฐ (- ฯ/4 imirasire cyangwa -0.7854 radians).
Shyiramo umubare mubi kugirango urebe uburyo arctan ikarita yinjiza nabi muburyo bubi.
Ibibazo
Ibisubizo kubibazo bisanzwe byerekeranye na tangent inverse.
Nibyo, tanโปยน ni imibare isanzwe yerekana imibare ihindagurika, nanone yitwa arctan witonda cyangwa arctan. Superscript โปยน ntabwo isobanura 1 / tan (ni cotangent). Ahubwo, tanโปยน(x) arabaza ati: 'Ni izihe mpande zifite tangent ingana na x?' Kurugero, tanโปยน (1) = 45 ยฐ kuko tan (45 ยฐ) = 1. Urashobora kandi kubona yanditse nka arctan(x) cyangwa atan(x) mundimi za programme.
Imikorere ya tangent ifata inguni igasubiza ikigereranyo cyuruhande rutandukanye kuruhande rwegeranye muri mpandeshatu iburyo. Impinduka ihindagurika (arctan) ikora ibinyuranye: ifata igipimo igasubiza inguni ihuye. Kurugero, tan (45 ยฐ) = 1, bityo arctan (1) = 45 ยฐ. Tangent ifite urwego rwimibare nyayo usibye kugwiza bidasanzwe kwa 90 ยฐ, mugihe tangent ihindagurika yemera imibare nyayo kandi igasohoka inguni hagati ya โ90 ยฐ na 90 ยฐ (- ฯ/2 kugeza kuri ฯ/2 radians).
Akabuto gahindagurika kicaye hejuru yurufunguzo kuri calculatrice ya siyanse. Kugirango uyigereho, kanda urufunguzo rwa 2 cyangwa Shift ubanza, hanyuma ukande buto ya tan. Iyerekana izerekana tanโปยน cyangwa arctan. Gufata ibara nka TI-84, kanda 2 hanyuma TAN. Kuri Casio kubara, kanda SHIFT hanyuma tan.
Koresha urutonde rwa Taylor kwagura: arctan(x) = x - xยณ / 3 + xโต / 5 - xโท / 7 + ... kuri |x| โค 1. Ku ndangagaciro zisanzwe, fata mu mutwe inguni zingenzi: arctan (0) = 0 ยฐ, arctan (1 / โ3) = 30 ยฐ, arctan (1) = 45 ยฐ, arctan ([7 Urashobora kandi gukoresha algorithm ya CORDIC. Ku ndangagaciro ziri hanze [โ1, 1], koresha indangamuntu arctan(x) = ฯ/2 - arctan (1 / x) kuri x> 0.
Impinduka zinyuranye za 1 ni 45 ยฐ (cyangwa ฯ/4 radians). Ni ukubera ko tan (45 ยฐ) = 1. Muri mpandeshatu iburyo aho impande zinyuranye kandi zegeranye zingana, inguni ni 45 ยฐ.
Igitereko gihindura inguni mu kigereranyo (gihabanye / cyegeranye), mugihe igitereko cyinyuma ([0]]) gihindura igipimo gisubira mu mfuruka. Tan ni igihe kandi irashobora gutanga umubare nyawo wose, mugihe arctan burigihe isubiza inguni idasanzwe murwego (โ90 ยฐ, 90 ยฐ).
Nibyo, koresha formula =ATAN(value) muri Excel. Ibi bisubiza ibisubizo muri radians. Guhindura impamyabumenyi, koresha =DEGREES(ATAN(value)). Excel nayo ishyigikira = ATAN2(x, y) kubitekerezo bibiri arctan byoroheje.
Hindura iphone yawe kugirango yerekanwe icyerekezo kugirango ugaragaze kubara siyanse. Kanda buto ya 2 kugirango uhindure imikorere itandukanye. Akabuto ka tan kazahinduka kuri tanโปยน. Injiza agaciro kawe hanyuma ukande tanโปยน.
Muri mpandeshatu iburyo, tangent ihindagurika yikigereranyo gihabanye / yegeranye ingana inguni kuri iyo vertex. Niba bihabanye = 3 kandi byegeranye = 4, noneho arctan (3/4) โ 36.87 ยฐ.
Hano haribikorwa 6 bisanzwe:
Binyuze kuri tan(ฮธ) = sin(ฮธ)/cos(ฮธ). Niba ฮธ = arctan(x), noneho sin(ฮธ) = x/โ(1+xยฒ) na cos(ฮธ) = 1/โ(1+xยฒ). Inkomoko ya arctan(x) ni 1/(1+xยฒ).
Yego. Ikigereranyo cyimisozi ni kimwe nikinyuranyo hejuru yegeranye na mpandeshatu iburyo. Injira kuzamuka kwawe nkuruhande rumwe no kwiruka kwawe nkuruhande rwegeranye kandi igikoresho gisubiza inguni ya mpinduramatwara muri dogere na radiyo.
Iki gikoresho cyubatswe byumwihariko kuri arctan witonda. Niba ukeneye imashini yuzuye ya trig calculatrice itwikiriye arcsin na arccos kuruhande arctan, uzakenera igikoresho kinini cya trigonometry.
