Ōwehenga Pākoki

Ko te kaupapa nei, he tūhura i ngā ōwehenga pākoki e rua nei, te aho (sin) me te whenu (cosine). Ka tirohia ngā ōwehenga o ngā tapa o tētahi tapatoru hāngai, me te whakamahinga o aua ōwehenga hei tātai i tētahi tapa, hei tātai rānei i tētahi o ngā koki.

Kia mōhio te ākonga ki:

  • ngā tikanga mō te whakaingoa i ngā tapa o tētahi tapatoru hāngai, arā, ko te tāroa, te tapa pātata me te tapa hāngai.
  • te tuhi hoahoa āwhata o te tapatoru hāngai, ka ine ai i te roa o ngā tapa. Mā konei e whakaputa ai i ngā ōwehenga pākoki mō te aho (sin) me te whenu300

Ko te kaupapa nei, he tūhura i te tikanga o tēnei mea te pātapa , he whakamahi hoki i te pātapa hei whiriwhiri i te roa o ngā tapa me te rahi o ngā koki o tētahi tapatoru hāngai. Kia rua wiki pea te roa o tēnei kōwae ako. I takea mai tēnei kōwae ako i te kōwae ako reo Ingarihi Investigating the Idea...

Kia mōhio te ākonga:

  • ki te whakamahi i ngā tikanga pātapa hei whakaoti rapanga e whai wāhi mai ana te tapatoru hāngai
  • ki te whakaoti whārite pēnei i te tan(θ) = a, mēnā kei waenganui i te 0° me te 360° te koki θ?’
  • ki te rahi o tan(θ) mō ēnei koki: 0°, 45°, 135°, 180°, 225°, 315°, 360°.
