RealRange
Agar siz x(a, b) ko`rinishda ko`rishni istamasangiz, berilagan o`zgaruvchini a<x, x< b tipda bo`lsa, figurali qavslarda ko`rsatish kerak.Masalan:
> solve(1-1/2*ln(x)>2,{x});
Tengsizliklar sistemasini yechish
solve buyrug’i yordamida tengsizliklar sistemasini ham yechish mumkin. Masalan:
> solve({x+y>=2,x-2*y<=1,x-y>=0,x-2*y>=1},{x,y});
Misol 1. Tengsizliklar sistemasi nechta butun yechimga ega?
Maple dasturida yechish:
> solve({3+4*x>=5, 2*x-3*(x-1)>-1},x);
Javob: Tengsizliklar sistemasi 3 ta butun yechimga ega.
Misol 2. Tengsizliklar sistemasini yeching.
Maple dasturida yechish:
> solve({x*(x+1)+10>(x+1)^2+3, 3*x-4*(x-7)>=16-3*x},x);
Misol 3. Tengsizliklar sistemasini yeching.
Maple dasturida yechish:
> solve({(y-5)/4<(2*y+3)/3, (4*y+1)/2<(y-4)/3},y);
Misol 4. Ushbu tengsizlikning barcha natural yechimlarini toping.
Maple dasturida yechish:
> solve({1256/314<9*x-32, 9*x-32<=2976/96},x);
Javob: Tengsizlikning natural yechimlari 5,6,7
Misol 5. Tengsizliklar sistemasining eng katta butun yechimini ko’rsating
Maple dasturida yechish:
