Imisebenzi Ye-Trigonometric
• Ukushintsha iyunithi ye-angle yokuzenzekela (amazinga, ama-radians,
ama-grads), cindezela inkinobho
izikhathi eziningana uze
ufinyelele kwisikrini sokusetha iyunithi ye-angle esiboniswe ngezansi.
• Cindezela ikhi yenombolo ( , , noma ) ehambelana neyunithi
ye angle ofuna ukuyisebenzisa.
(90° = π /2 yama-radians = 100 wama-grads)
