Video: Yuav ua li cas koj muab cov matrices ntawm lub graphing tshuab xam zauv?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
- Kauj ruam 1: Nkag mus rau thawj matrix rau hauv tshuab xam zauv . Nkag mus rau a matrix , nias [2ND] and [x−1].
- Kauj ruam 2: Nkag mus rau qhov thib ob matrix rau hauv tshuab xam zauv . Nias [2ND] thiab [x−1].
- Kauj ruam 3: Nias [2ND] thiab [MODE] tawm ntawm lub matrix npo.
- Kauj ruam 4: Xaiv matrix A thiab matrix B hauv NAMES ntawv qhia zaub mov kom pom cov khoom.
Kuj nug, ua li cas koj muab cov matrices ntawm TI 83?
Multiplying Matrices : Matrix sib npaug yog ib qho yooj yim rau ntawm TSI - 83 /84. Rau scalar kev sib npaug , ntau tus lej lub sijhawm matrix ib yam li kev sib npaug ob tug lej ua ke. Piv txwv li, rau ntau 3x ua matrix [A], ntaus В → ¯ → “Npe” → xaiv [A] → Н → Н.
puas qhov kev txiav txim tseem ceeb hauv matrix multiplication? Matrix multiplication yog tej zaum yog thawj zaug uas Commutative Property tau muaj teeb meem. Zoo, tam sim no Txoj Cai ntawm Kev Sib Txuas Lus tsis muaj teeb meem , vim kev txiav txim tseem ceeb rau matrix ntau . Nco ntsoov nco ntsoov tias, rau matrices , AB yuav luag ua tsis sib npaug BA.
Kuj Paub, Kuv yuav rov pib dua kuv lub tshuab xam zauv li cas?
Nrog rau qhov tsis lees paub tau hais, ntawm no yog yuav rov pib dua li cas:
- Nias 2nd MEM (uas yog qhov ua haujlwm thib ob ntawm tus yuam sij +)
- Xaiv 7 (Reset)
- Scroll txoj cai kom txhua tus raug xaiv.
- Nias 1.
- Nyem 2 (Pib dua, thiab nyeem cov lus ceeb toom)
Dab tsi yog qhov inverse ntawm matrix?
Rau ib square matrix A, cov thim rov qab yog sau A-1. Thaum A tau muab faib ua A-1 qhov tshwm sim yog tus kheej matrix I. Tsis-square matrices tsis muaj inverses. Lus Cim: Tsis yog tag nrho cov square matrices muaj inverses.

Rref txhais li cas ntawm lub tshuab xam zauv graphing?
Txo Kab Echelon Form - A.K.A. rref kev. Rau qee qhov laj thawj peb cov ntawv tsis tau txhais rref (Raws Kab Echelon Form) thiab yog li peb txhais nws ntawm no. Feem ntau cov graphing tshuab xam zauv (TI-83 piv txwv) muaj rref muaj nuj nqi uas yuav hloov ib qho matrix rau hauv daim ntawv txo qis echelon siv lub npe hu ua theem pib ua haujlwm
Lub zog zoo li cas yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm?
Kab nyob rau sab saum toj ntawm lub tshuab xam zauv. Ua li cas lub zog yog lub teeb lub zog hloov dua siab tshiab kom lub tshuab xam zauv ua haujlwm? Lawv hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob. zaub mov
Yuav ua li cas koj pom cosine ntawm lub tshuab xam zauv scientific?
Nias lub pob 'Cos', feem ntau pom nyob nruab nrab ntawm lub tshuab xam zauv. 'Cos' yog luv luv forcosine. Koj lub laij lej yuav tsum tso saib 'cos.'Sau qhov ntsuas ntawm lub kaum sab xis koj xav paub cov cosineratio ntawm
Yuav ua li cas los hloov ib tug quadratic kab zauv los ntawm vertex daim ntawv rau lub tshuab xam zauv?
Lub laij lej rau kev hloov pauv los ntawm daim ntawv yooj yim mus rau vertex daim ntawv y = x2 + 3x + 5. x2 + 3x + 5 = || +(p2)2-(p2)2=0. || a2+2ab+b2=(a+b)2. || -1⋅-1=+1. xS=-32=-1.5. yS=-(32)2+5=2.75
Koj siv cov lej xav li cas ntawm lub tshuab xam zauv?
Koj lub laij lej tsuas qhia tau cov lus teb yooj yim, raws li pom hauv thawj qhov screen. Cov lej tsis sib xws yuav tsis raug siv nrog tus qauv n/d feem. Hloov chaw, sau cov lej tsis sib xws ua cov zauv feem siv cov kab lus thiab tus yuam sij faib. Nias [MATH][ENTER][ENTER] los tso saib cov lus teb nyuaj rau hauv daim ntawv feem
