Xcas, the swiss knife for mathematics,^[7] er et frit,^[8] open source^[9] computerprogram til brug i regning og matematik. Xcas er et Computer Algebra System (CAS),^[10] der kan løse ligninger (fig. 4) og differentialligninger (fig. 6) m.m. ved symbolmanipulation.^[11]

Basalt set er Xcas en brugergrænseflade til Giac,^[12] som er skrevet i programmeringssproget C++^[13] og Xcas virker i offline-tilstand til flere styresystemer.^[14]

Features (uddrag)

Flere af disse features er fælles for Xcas & GeoGebra:^[15]

Xcas er bl.a. en basal lommeregner, der kan skrive pretty print ligesom LaTeX^[16] og flere equation editors. Dertil kommer, at Xcas kan vise input.
Xcas fungerer også som regneark.^[17]
faktorisere polynomier
tegne funktioners grafer (såvel 2-d som 3-d)^[18]
løse ligninger^[19] endda med komplekse rødder eller komplekse løsninger^[20] (fig. 4)
løse trigonometriske ligninger
løse differentialligninger^[21]^[22] (se fig. 6 og tabel nedenfor)^[23]
beregne differentialkvotienter og dermed differentialregning^[24] (se fig. 5)
beregne stamfunktioner og således integralregning^[25] (se fig. 5)
beregne arealer og bestemte integraler
beregne flere regressionstyper (eksponentiel, lineær,^[26] logaritmisk, logistisk, polynomial, potens)
programmering^[27]^[28]

Kommandoer (uddrag)

Uddrag af manualen Symbolic algebra and Mathematics with Xcas:^[29]

Kvadratrod: sqrt(49) = 7
propfrac(42/15) = 2+4/5

Beregne standardafvigelse: stddev([3,4,2]) = sqrt(2/3)
Beregne varians: variance([3,4,2]) = 2/3
Beregne lokale ekstrema: extrema(-2*cos( $x$ )-cos( $x$ )^2, $x$ ) = [0],[pi]

Foretage separation af de variable: split( $x$ +1)*( $y$ -2),[ $x$ , $y$ ) = [ $x$ +1, $y$ -2]
Løse differentialligning (differentialligningens højre-side skrives som $y'=$ eller $y''=$ ): desolve(differentialligning, $y$ ) f.eks. desolve( $y'=k\cdot y,y$ ) eller desolve( $y''=k\cdot y,y$ )

Styresystemer

Xcas findes til flere styresystemer:^[14]

Xcas kan også anvendes online.^[36]

Xcas & GeoGebra

Historie

Xcas er open-source-projekter^[37] udviklet af en gruppe ledet af den franske matematiker Bernard Parisse^[38]^[10] ved Joseph Fourier-universitetet^[39] i Grenoble (Isère), Frankrig, siden år 2000.^[40] Xcas og Giac er baseret på erfaringer opnået med Parisses tidligere projekt Erable.^[41] I 2013 blev Xcas integreret med det østrigske CAS-program GeoGebra,^[13] der anvender Xcas som CAS-kerne.^[7] Integrationen mellem Xcas & GeoGebra er sket, selvom GeoGebra er skrevet i java.^[42] Siden 2013 findes forklarende videoer om Xcas^[43] online.^[44] OpenOffice.org anvender Xcas til beregninger.^[45]

Xcas & GeoGebra anvendes i undervisning

Siden år 2000 har Xcas, the swiss knife for mathematics, opnået at blive meget udbredt i det franske uddannelsessystem;^[46] Også spanske og mexicanske uddannelsesinstitutioner har taget Xcas til sig.^[47] Nogle tyske^[10]^[48] og amerikanske universiteter anvender Xcas: University of North Carolina Wilmington^[49] og University of New Mexico.^[50]

I Danmark anvendes Xcas & GeoGebra og andre programmer

På trods af integrationen mellem Xcas og GeoGebra, så har Xcas i Danmark^[51] har endnu kun fundet begrænset anvendelse.^[52] Derimod anvender folkeskolen^[53] GeoGebra meget^[54] som supplement til LibreOffice^[55] regneark (Calc) og equation editor (Math).^[56] Gymnasier anvender både GeoGebra,^[57] TI-NSpire og Maple,^[58] mens universiteter^[59] anvender Maple.^[60]

Xcas & GeoGebra er CAS-programmer blandt flere

Flere kommandoer for Xcas er kompatible med kommandoer til flere programmer,^[61]^[62] f.eks. Wolfram Alpha,^[63] Mathematica,^[64] Maxima,^[65] Maple,^[66]^[67] Matlab,^[68] Yacas,^[69]^[69] SageMath,^[70] Singular,^[71] MuPAD, Qcas, CPMP-Tools,^[72]^[73] WordMat (addon til Microsoft Word^[74]) og ExpressionsinBar (64 bit app for macOS^[75]^[76]) samt Graphmatica^[77] og Kig.^[78]^[79] Grafregnerne TI-89, TI-92,^[80] Voyage 200 og TI-Nspire^[18] rummer også kommandoer, som udviser ligheder med Xcas.^[18] Der er et forum for spørgsmål om Xcas.^[81]
