Oddiy tenglamalarni yechish
Maple da tenglamalarni yechishning universal buyrug’i solve(eq,x)bo`lib, bu yerda eq – tenglama, x – o`zgaruvchi, qaysiki tenglamani yechimini bera oladigan. Bu buyruq to`la samarali bo`lishi uchun kiritish satrida ifoda to`la yoritilishi kerak. Masalan:
> solve(a*x+b=c,x);
Misol 1. ni toping. 420 : ( 160 – 1000:)=12
> solve(420/(160-1000/x)=12,x);
Misol 2. Tenglamani yeching. 6,9 : 4,6 = : 5,4
> solve((6.9/4.6=x/5.4),x);
Misol 3. tenglamani yeching.
> solve((x/3+x/15+x/35+x/63+x/99+x/143)=12,x);
Misol 4. tenglamani yeching.
> solve(((3*x-2)/4+(2*x+3)/2-2.5*x+2)=0,x);
Agar tenglama bir necha yechimga ega bo`lsa, name buyrug’i orqali boshqa hisoblash amallarini bajarishda yechimlarni tanlab olamiz. Berilgan tenglamaning k- yechimini aniqlash uchun kvadrat qavslar ichida yechim tartibini ko`rsatish lozim: name[k]. Masalan:
