Chiziqli tenglamalar sisitemacini yechish

Maple7 dasturida masalani echish.
> with(Student[LinearAlgebra]):

> A := <<2,3,5>|<7,14,25>|<13,12,16>>;

Matritsaviy tenglamani echish
Quyidagi matritsaviy tenglamani undaagi koeffitsent matritsaga teskari matritsa topish bilan echamiz.

Yuqorida keltirilgan formula (*) va (**) formulalar

,

asosida echish uchun oldin ni topamiz va unga B matritsani ko‘paytiramiz. Bu amalni Maple 7 dasturida quyidagicha bajaramiz:

> with(Student[LinearAlgebra]):

> A := <<1,0,1>|<3,1,-1>|<-1,-2,0>>;



> A^-1:=A^(-1);



> B := <<13,2,-2>|<-4,-4,5>|<6,2,5>>;



> X:=A^(-1).B;

Quyidagi masalalarni echishmni to‘g‘ridan-to‘g‘ri Maple7 dasturida bajarilishini ko‘rsatamiz.

Uchburchak tomonlarining o‘rtalaridan o‘tkazilgan aylana:
