Which mathematical challenge arises when medieval Islamic engineers attempted precise qibla determination through spherical trigonometry?

💡 Explanation

When calculating the qibla, cubic equations arose from derivations applying spherical triangles; therefore explicit solutions using algebraic manipulation would simplify iterative trigonometric approximations improving accuracy. Thus deriving cubic equation solutions is correct rather than other choices which are distinct areas of mathematics.
