Leej twg tsim lub 3 qhov tseem ceeb trig ratios?

Astronomy yog lub zog tsav tom qab kev nce qib hauv trigonometry. Feem ntau ntawm cov kev nce qib thaum ntxov hauv trigonometry yog nyob rau hauv spherical trigonometry feem ntau vim nws siv rau astronomy. Peb lub ntsiab lus tseem ceeb uas peb paub hauv kev txhim kho Greek trigonometry yog Hipparchus , Menelaus, thiab Ptolomy.
