Ma kēia hoʻolaha, e noʻonoʻo mākou i ka wehewehe ʻana, ka wehewehe geometric, ka pakuhi o kahi hana, a me nā laʻana o ka modulus o kahi helu maikaʻi/negative a me ka ʻole.
Ka hoʻoholo ʻana i ka modulus o kahi helu
Modulus Helu Maoli (kapa ʻia i kekahi manawa waiwai piha) he waiwai like me ia inā he maikaʻi ka helu a i ʻole like me ka ʻaoʻao inā he ʻino.
Ka waiwai piha o kahi helu a hōʻike ʻia e nā laina kūpaʻa ma nā ʻaoʻao ʻelua o ia - |a|.
helu kūʻē ʻokoʻa mai ka hōʻailona kumu. No ka laʻana, no ka helu 5 ʻo ke kūʻē -5. I kēia hihia, kū'ē ka zero iā ia iho, ʻo ia hoʻi
Ka wehewehe Geometric o ka module
Modulus o a ʻo ka mamao mai ke kumu (O) i kahi lae A ma ke axis coordinate, e pili ana i ka helu aIe
|-4| = |4| = 4
Kiʻi hana me ka Modulus
Kipi o ka hana like y = |х| penei:
- y=x me x> 0
- y = -x me x <0
- y = 0 me x = 0
- kahua o ka wehewehena: (−∞;+∞)
- laula: [0;+∞).
- at x = 0 haki ka pakuhi.
Laʻana o kahi pilikia
He aha kēia mau modules |3|, |-7|, |12,4| a |-0,87|.
Hoʻoholo:
E like me ka wehewehe i luna:
- |3| = 3
- |-7| = 7
- |12,4| = 12,4
- |-0,87| = 0,87
