Which outcome improves through applied algebra when positioning the alidade on a historical universal astrolabe?

💡 Explanation

When using an astrolabe, small errors in physically aligning the alidade cause significant angular errors in altitude measurements; algebra's geometric and trigonometric principles are used to minimize these errors prospectively through adjusted readings. Therefore accuracy of altitude measurements improves, rather than stability, speed increases or stress which are not directly related to corrective calculations.
