Xws li listes 3 nta GeoGebra, uas ua tau hauj lwm nrog lub npe ntawm randomness rau kev qhia ntawv. Zog tau siv nyob rau hauv lub thawv input, i regnearket, thiab thaum twg ib tug codes fx nyees khawm.

Koj yuav ua li cas

TilfældigMellem[ <Yam tsawg kawg nkaus Integer>, <Integer siab tshaj> ]

Yog ib tug muaj nuj nqi, uas ua tau mus GeoGebra ua tilfældigetal tus zauv ntawm tsawg kawg- thiab tus nqi uas siab tshaj plaws. Neb ob leeg tes.

1. Ntaus ntawv nyob rau hauv lub thawv input

   TilfældigMellem[1,6]

2. Nias F9 saum tus keyboard txais lub feature mus generére random qhov tseem ceeb.

Random caij[Sau]

Cov nuj nqi pub rau xaiv random tus nqi ntawm ib daim ntawv teev predetermined. Ua ntej lub npe, thiab ces siv lub.

1. Koj yuav tsum ua ib daim ntawv teev ua ntej. Ntaus ntawv nyob rau hauv lub thawv input

   Listbox1 = {-3,00,02,4,7,10,12}

2. Siv kev ua

   Random caij[Listbox1]

3. Xovxwm F9 saum tus keyboard txais lub feature mus generére random qhov tseem ceeb los ntawm daim ntawv.

Random Polynomial[ <Kawm ntawv>, <Yam tsawg kawg rau Coefficients>, <Tshaj plaws rau Coefficients> ]

Muaj peev xwm ua kom muaj zog random.

1. Ntaus ntawv nram qab no nyob rau hauv lub thawv input

   Random Polynomial[3,1,3]

2. Nias F9 saum tus keyboard txais lub feature mus generére random qhov tseem ceeb

Ntsis

• Thaum twg koj tau sau ib yam dab tsi los ntawm cov npe ntawm cov nuj nqi, ces los txog lub GeoGebra txiav cov proposals. Nias sau rau hauv koj cov keyboard los xaiv lub tswv yim txog.
• Siv cov xub mus rau txoj kev thiab laug xub dhia ntawm qhov chaw rau cov yam ntxwv.
