A cikin wannan ɗaba'ar, za mu yi la'akari da ma'anar, fassarar geometric, jadawali na aiki, da misalan ma'auni na ingantacciyar lamba / mara kyau da sifili.
Ƙayyade ƙimar lamba
Modul Modul na Gaskiya (wani lokacin ake kira cikakken darajar) darajar daidai yake da ita idan lambar ta kasance tabbatacce ko daidai da kishiyar idan ta kasance mara kyau.
Cikakken ƙimar lamba a wanda aka nuna ta layukan tsaye a ɓangarorinsa biyu - |a|.
kishiyar lamba ya bambanta da alamar asali. Misali, ga lamba 5 akasin haka shine -5. A wannan yanayin, sifili ya saba wa kanta, watau
Fassarar Geometric na module
Modul a shine nisa daga asalin (O) zuwa wani batu A akan ma'aunin daidaitawa, wanda yayi daidai da lamba aIe
|-4| = | 4| = 4
Aiki Graph tare da Modulus
Graph na wani madaidaicin aiki y = | mai bi:
- da = x tare da x>0 ku
- y = -x tare da x <0
- yi = 0 tare da x = 0
- yankin ma'anar: (-∞ +∞)
- iyaka: [0+∞).
- at x = 0 ginshiƙi karya.
Misalin matsala
Menene waɗannan kayayyaki masu zuwa |3|, |-7|, |12,4| kuma |-0,87|.
Yanke shawara:
Bisa ga ma'anar da ke sama:
- |3| = 3
- |-7| = 7
- |12,4| = 12,4
- |-0,87| = 0,87
