In the proportional semi-arc method, the only formula needed is the one for mixed ascensions. Directions to the Ascendant (oblique formula) and the MC (simple subtraction) are simplified special cases where the formula can be reduced from the method of mixed ascensions.jventura wrote: In section 4 of the post, I show one simple formula which is generic enough to solve the three mentioned problems in the same way. I demonstrate mathematically that the formula is adequate to solve each of the single "problems". The formula is just another way of expressing the semi-arc method, but it seems simpler to me...
