Which navigational problem became solvable circa 1000 AD due to significant advances in algebra?

💡 Explanation

Calculating lunar position used algebra to resolve angular differences; the method of double angle formulas provided solutions where classical geometry alone failed, because algebraic manipulation allowed more precise angle calculation, therefore enabling better lunar positioning rather than relying primarily on observation.
