4.9-rasm. Simvolli hisoblashlarni bajarish.
Simvolli hisoblashlarni bajarishda ikkita asosiy vosita mavjud:
• Symbolics (Simvolli hisoblash) menyusi;
• Matematika panelidan Symbolic paneli.
Bu vositalar ancha murakkab simvolli hisoblashlarda qo’llaniniladi. Hozir esa oddiy simvolli
hisoblashni bajarishning eng sodda usuli, ya’ni tez-tez ishlatilib turiladigan usullardan biri -
simvolli tenglik belgisi (→) usulini ko’rib chiqamiz. Quyida bu usuldan foydalanishning ketma-
ketlik tartibi berilgan:
1. Matematika panelidan Calculus Toolbar (Hisoblash paneli) tugmasi bosiladi.
2. Ochilgan panel oynasidan Calculus (Hisoblash) ni tanlab, aniqmas integralni sichqonchada
chiqillatiladi (misol tariqasida aniqmas integral qaralayapdi).
3. Kiritish joylari to’ldiriladi, ya’ni funksiya nomi va o’zgaruvchi nomi kiritiladi.
4. Simvolli belgi tengligi (→) belgisi kiritiladi.
