  1. Kauj ruam 1: Nkag mus rau thawj matrix rau hauv tshuab xam zauv . Nkag mus rau a matrix , nias [2ND] and [x−1].
  2. Kauj ruam 2: Nkag mus rau qhov thib ob matrix rau hauv tshuab xam zauv . Nias [2ND] thiab [x−1].
  3. Kauj ruam 3: Nias [2ND] thiab [MODE] tawm ntawm lub matrix npo.
  4. 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:

  1. Nias 2nd MEM (uas yog qhov ua haujlwm thib ob ntawm tus yuam sij +)
  2. Xaiv 7 (Reset)
  3. Scroll txoj cai kom txhua tus raug xaiv.
  4. Nias 1.
  5. 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.
