GeoGebra yog lub weekend lub nyob rau hauv ib tug tshiab version. Ntawm no koj yuav tau nyeem txog ib co ntawm cov kev hloov thiab kev txhim kho, uas tau tuaj mus rau. Muaj kom txaus yuav zoo siab nyob rau hauv no tshiab version.

Tshiab:Nyob rau hauv thawj version 4.2.1.0, men der er i skrivende stund blevet udsendt en ny version 4.2.2.0.
Tshiab: Endnu en ny version 4.2.3.0

Tshiab nyob rau hauv version 4.2 – Me me txog

Ceev code – Loj qhov chaw hauv code tau sau ib tsab ntawv hais txog, ua suav m.m. ceev.

CAS
Nu er den længe ventede CAS kommet i GeoGebra. Ntawm no, nws yog ib qhov ua tau kom tau GeoGebra rau e.g. tau kev daws mus rau equation,, shortening fractions, nrhiav seb ib tug xov tooj yog Prime, m.m.
By nta kuv tau hais:

ErPrimtal[ <cov zauv> ]
Next Prime[ <cov zauv> ]
Previous Prime[ <cov zauv> ]
Divisors[ <cov zauv> ]
Divisorliste[ <cov zauv> ]
Divisorsum[ <cov zauv> ]
TilfældigPolynomium[ <Qib>,<Yam tsawg kawg nkaus Coefficients>,<Siab tshaj plaws ntawm Coefficients> ]

Sim mus sau “2x 4 = 5x 6” i CAS-vinduet. Tsis txhob nias Rov qab mus / Sau, tiam sis tsuas yog nyob rau hauv -khawm. Yog li qhov equation. Koj tseem yuav siv tib txoj, txawm yog hais tias koj sau lwm cov npe tshaj x. Piv txwv li, koj yuav xam lub ib voos ncig ntawm ib lub voj voog, Yog hais tias tus circumference yog npaj.

Tshiab Tool

Freehand daim ntawv -khawm – Qhov no khawm cia koj kos ib tug duab nyob rau hauv nyob rau hauv GeoGebra freehand thiab ces yuav GeoGebra kos cov duab. Piv txwv li cov cim qhia ib square nyob rau hauv freehand thiab nws yuav raug npaum li cas tom qab.

Duab kev kho me ntsis

Tshiab desktop icon – Tam sim no nrog dawb background.

Me me ntawm no kev kho me ntsis thiab muaj. Piv txwv li. nicer icon “Mem twj” .

Gitter og akser er nu forsvundet fra menuen ‘Vis’. Txawm li ntawd los, nws muaj peev xwm tseem yuav pom los ntawm txoj cai-nias on “Kos block” thiab xaiv “Kab sib chaws / Axes“.

Tsis tas li ntawd, muaj tau xaiv lub foundations ntawm sab xis ntawm qhov kev pab cuam. Siv lub thawv nyob rau sab xis thiab tau txais ib daim zaub mov txawv ntawm txoj kev faib lub khawm on.

Liab cheeb tsam ntawm lub Toolbar khawm tam sim no ncig los ntawm ib tug grey lub voj voog.

Hloov style Bar – Hauv qab no lub Toolbar koj ua tau tam sim no rau sab laug sab, rov qab sab ntawm nplooj ntawv ua ntej, saib icon cov ua cim los ntaub qhwv to .

Thaum koj kos nrog “Mem twj” , ces muaj qhov style bar nrog ib tug knappenål “Meej txoj hauj lwm ntawm qhov screen”. Yog hais tias koj nyem qhov nyob rau hauv, yog li enlarged / txo tus, uas koj tau subscribed, thaum koj nyob rau hauv Zoom- los yog tawm Zoom-.

Khawm sij hawm – Nws yog tam sim no ua tau kom siv ib daim duab on khawm. Neb ob tus qauv khawm los yog tus kheej image (Xaiv los ntawm cov ntaub ntawv). Pom tau tias nws los ntawm txoj cai-nias lub khawm thiab xaiv khoom. Tom qab ntawd ces xaiv lub tab “Nug”.

Tus cawm khawm yog ploj mus – Tam sim no hloov tawm chaw, thaum, rau Piv txwv li, txoj cai-nias lub kos thaiv thiab xaiv “Tegneblok…” (yav tas los thaj chaw). Yav tsim tseem ntau tshaj li yoob zoo.

Ntau qhov chaw xaiv

Muaj ntau ntau yam tshiab txhim kho / hloov mus rau lub chaw xaiv.

Piv txwv li, koj muaj peev xwm tam sim no yooj yim hloov qhov layout siv. khawm nyob rau hauv khoom. Txoj cai-nias lub kos thaiv thiab xaiv “Nta”.

Hloov ntawm degrees thiab radians.

 

Tshiab nta

Nws muaj ib tug ntau ntawm tshiab nta mus rau lub tswv yim teb (koj tig lub tswv yim mus rau lub teb submenu qhia). Tag nrho 93 Tag nrho. Feem ntau ntawm cov kev ua hauj lwm on statistics.

Mus saib nyob rau hauv kev.

Lwm yam

Lub analytical cuab yeej nyob rau hauv lub spreadsheet – Ib variable Analysis thiab Ob-variable tsom xam cov cuab yeej muaj ob leeg tau tshiab.

Nye tastatur-genveje – En del nye tastatur-genveje er kommet til i den nye version.

Javascript – Tshiab javascript lus txib.

Stair Chart – Tam sim no koj tau qis cua charts siv. tawm tswv yim dab tsi. Skriv fx trappediagram…, koj yuav saib tau qhov ntau tau Honor.

Tawm tswv yim teb Historikk – Tryk li xub rau ntawm keyboard thiab cov tas los lus txib.

Algebra qhov rais

 

 

 

Værktøj – Muaj tam sim no tshiab tau Honor uas qhia lawv tus kheej værktøj, hais tias nyob rau hauv lichen Menuet “Cov cuab yeej”.

Qhia piv txwv li khawm.

 

 

 

Txhim kho cov tswv yim:

Delete khoom – Ib tug ua tau tseem, thaum twg koj tau xaiv “Delete khoom”, khob rau tej khoom mus tshem lawv. Yog dab tsi tshiab yog, hais tias koj muaj peev xwm cab koj nas thoob plaws ntawm daim duab thaiv thiab lwv tej khoom los yog qhov chaw hauv kos khoom.

Hla nruab nrab ntawm ob tug tej khoom – Lub khawm yog tam sim no tseem nyob nruab nrab ntawm cov khoom thiab lees paub (siv. ) tej khoom.

Muaj ob peb yam kev txhim kho thiab kev hloov rau khawm nrog vectors.

 

Koj muaj peev xwm nrhiav tau ib daim ntawv teev tag nrho cov tshiab rau ntawm cov nram qab no txuas:
