  1. Cydrannu Grymoedd Oes modd rhannu’r grym yma’n un grym i gyfeiriad x, ac un arall i gyfeiriad y? 12N

  2. Defnyddio trigonometreg i gyfrifo maint y cydrannau x ac y. 12N Cydrannu’n fertigol Cydrannu’n llorweddol

  3. Felly: 12N 6.88N 9.83N

  4. Cydrannwch: 28N 28sin41N 28cos41N 18.37N 21.13N

  5. Cyfrifwch gydeffaith y grymoedd yma: 8N 8sin28N 3+8cos28N 3N Felly cydrannau’r grym cydeffaith fydd: 3.76N 10.06N

  6. Nawr, rhaid cyfrifo cydeffaith y grymoedd: C 3.76N 10.06N

  7. Felly cydeffaith y grymoedd fydd 10.74N ar ongl o 20.5° uwchben y grym gwreiddiol o 3N 8N 10.74N 3N

  8. Beth fydd cydeffaith y grymoedd yma: 7N 5N 4N

  9. Felly bydd cydrannau x ac y yn: Nawr rhaid cyfrifo’r cydeffaith: Cydeffaith y grymoedd fydd 3.07N ar ongl o 5.9° uwchben y llorweddol 3.07N
