I am relatively new to the concepts of trigonometry but have stumbled upon a problem. Is there an actual method to determine values of sine, cosine and tangent without using calculators?

it depends on what values are you searching. Some values like 30, 45, 60, 18, 36, 54, 72 and their relatives in the other quafdrants can be determined using basic geometry basic geometry, other ones can be also found using trigonometry relations

I mean angles under 180 degrees. I am asking for the actual method or formula to determine the values.
