Given a unit-hypotenuse triangle, how do we get the inverse sin/cos/tan equations? I'm trying to program a high-precision fixed-fraction model of the sun and earth and I've forgotten how the equations are derived. I know there's differentiation and integration. And I'm stuck on how to express the relation between opp/adj as angle.(adsbygoogle = window.adsbygoogle || []).push({});
