Xulosa.


Hozirgi vaqtda kompyuterlarda ilmiy-texnikaviy hisoblashlarni bajarishda odatdagi dasturlash tillaridan va elektron jadvallaridan emas, balki Mathematica, MatLab, Maple, Gauss, Reduse, Eureka va boshqa turdagi maxsus matematik dasturlar keng qo’llanilyapti.


Maple dasturining Inpakx yordamida turli kasb egalari o’z sohasi bo’yicha masalalarni hal etishi va kerakli grafiklarni, diagrammalarni olishi mumkin. Bu dastur imkoniyatlaridan kelib chiqib, uni tayyor paket deyish mumkin. Maple yuqori interfeysga ega bo’lib, turli matematik va texnik masalani tez yechish, ularning grafiklarini qurish va animatsiya effektlaridan foydalanish inkonini beradi. Maple tizimida masalalarni sonli yechish bilan bir qatorda analitik usulda yechish hisobga olinadi.
Ushbu bitiruv malakaviy ishida Maple tizimining interfeysi, Maple tizimining funksiya va buyruqlari, Maple tizimida analitik hisoblashlarni bajarish, turli ko’rinish va xarakterdagi tenglamalarni Inpakx paketida yechish usullari, ya’ni tenglamalar va tenglamalar sistemasini yechish, tengsizliklar va tengsizliklar sistemasini yechish, trigonometrik va transendent tenglamalarni yechish kabi usullar haqida to’liq ma’lumot berilgan bo’lib, bu usullardan Maple tizimida hal etish misollar orqali tushuntirilgan.
Shuning uchun, foydalanuvchilar bu dasturdan o’zlari yecha olmagan matematik masalalar uchun tayanch yechim ombori sifatida foydalanishlari mumkin. Shuningdek, differensial tenglamalarni yechish, statistika, termodinamika, boshqaruv nazariyasi kabi jarayonlarni geometrik tasvirlash va animatsiyalar orqali ijro etishni yuqori darajada amalga oshirish mumkin. Bu tizimdan tabiiy fanlar bo’yicha elektron darsliklar yaratishda asos dasturiy vosita sifatida foydalanishni tavsiya etish mumkin.
Bularning barchasi o’quvchida ijodiy, mantiqiy va mustaqil fikrlashni rivojlanishiga, hamda yangi ob’ektlarni har tomonlama o’rganish va shu asosda o’zining mulohazalarini izhor etish imkonini beradi.
Ushbu bitiruv malakaviy ishida yoritilgan tushunchalardan, taklif etilgan usullardan va yechilgan masalalardan aniq fanlarni o’qitishda, ilmiy tadqiqot va muhandislik ishlarini bajarishda foydalanish mumkin.
