生成这个题目的讲解---**Question Stem:** 14. 若双曲线 y² - (x²/m²) = 1 (m > 0) 的渐近线与圆 x² + y² - 4y + 3 = 0 相切, 则 m = ______. **Explanation of Mathematical Formulas/Equations:** * **Hyperbola equation:** y² - (x²/m²) = 1 * This is a hyperbola centered at the origin, with its transverse axis along the y-axis. * Condition: m > 0. * **Circle equation:** x² + y² - 4y + 3 = 0 * This is the general form of a circle equation. It can be rewritten in standard form (x - h)² + (y - k)² = r² to identify its center and radius. **Other Relevant Text:** * "若双曲线...的渐近线与圆...相切" translates to "If the asymptotes of the hyperbola... are tangent to the circle...". * "则 m =" translates to "then m =". The question asks to find the value of m.
