Te tātaitai tawhiti i waenganui i ngā ira e rua
Ka kitea te tawhiti o te raina hāngai i waenganui i ngā pito e rua i runga i te rererangi.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
the distance formula, d = √((x₂ − x₁)² + (y₂ − y₁)²), is simply the Pythagorean theorem applied to a grid: the horizontal and vertical gaps are the two legs of a right triangle and the distance is the hypotenuse. Between (0, 0) and (3, 4), Δx = 3 and Δy = 4, so d = √(3² + 4²) = √(9 + 16) = √25 =
Ko nga pātai e pā ana
He aha te tātai tawhiti?
Ko d = √((x2 − x1)² + (y2 − y1)²). I waenganui i te (0,0) me te (3,4) ko te tawhiti ko te √(9 + 16) = √25 = 5.
He pēhea te pātahitanga ki te kupu Pythagorean?
Ko ngā mokowā whakawhāiti me ngā mokowā poutū e hanga ana i ngā kōpaka e rua o tētahi tapawhā tika, ā, ko te tawhiti ko tōna pātata — nō reira ko te tātai tawhiti ko Pythagoras i runga i te kāwai.
He aha te Δx me te Δy?
Ko ēnei ngā rerekētanga pāwhewa me te poutū i waenganui i ngā ira, x2 − x1 me y2 − y1 — ko ngā kōaro e rua o te tapawhā tika i muri i te tawhiti.
E whakaatu ana te utauta i te wāhi waenganui?
He. I te taha o te tawhiti e hoatu ana e ia ki te pito matua, ko te taururuku e tika ana te waenganui i waenganui i ngā pito e rua.
He mea hira te raupapa o ngā ira?
Kāore. He tapawhā nga rerekētanga, nō reira ko te whakawhitinga i ngā pito e rua e tuku ana i te tawhiti ōrite.
Ka taea e ia te whakahaere i ngā taururuku tōraro?
He. He mahi ngā taururuku tūturu katoa, tae atu ki ngā tōraro me ngā ira — ka pupuri te tapawhā i ngā tawhiti tōrunga katoa.
API — whakamahi tēnei tātaitai mai i te waehere
E kī ana tēnei tātaitai hei wāhi mutunga kore JSON - kāore he kī e hiahiatia ana. Ka tukuna ngā uara āpure i raro nei hei tohutoro pātai, JSON rānei. Ka pānui te papatono API katoa →
