tirotiro
I roto i tenei whakaputanga, ka whai whakaaro tatou ki te whakamaramatanga, te whakamaoritanga ahuahanga, te kauwhata o te mahi, me nga tauira o te waahanga o te tau pai/kino me te kore.
Te whakatau i te waahanga o te tau
Tau Tuturu Modulus (i etahi wa ka karangahia uara tino) he uara e rite ana ki a ia mena he pai te tau, he rite ranei ki te keehe mena he toraro.
Te uara tino o te tau a e tohuhia ana e nga raina poutū i nga taha e rua - |a|.
tau ritenga he rereke ki te tohu taketake. Hei tauira, mo te tau 5 ko te ritenga ke -5. I roto i tenei take, ko te kore he rereke ki a ia ano, a
Te whakamaoritanga ahuahanga o te kōwae
Kōwae o a ko te tawhiti mai i te takenga (O) ki tetahi waahi A i runga i te tuaka taunga, e rite ana ki te tau aIe
|-4| = |4| = 4
Kauwhata Mahi me te Modulus
Kauwhata o te mahi taurite y = |х| e whai ake nei:
- y=x mā te x> 0
- y = -x mā te x <0
- y = 0 mā te x = 0
- rohe whakamārama: (−∞;+∞)
- awhe: [0;+∞).
- at x = 0 ka pakaru te tūtohi.
He tauira o te raruraru
He aha nga waahanga e whai ake nei |3|, |-7|, |12,4| me |-0,87|.
Te whakatau:
E ai ki te whakamaramatanga i runga ake nei:
- |3| = 3
- |-7| = 7
- |12,4| = 12,4
- |-0,87| = 0,87
