It is known that hyperbola C1 and hyperbola C2: y ^ 2 / 4-x ^ 2 / 9 = 1 have the same asymptote And through the point m (9 / 2, - 1), the standard equation of hyperbola C1 is obtained

It is known that hyperbola C1 and hyperbola C2: y ^ 2 / 4-x ^ 2 / 9 = 1 have the same asymptote And through the point m (9 / 2, - 1), the standard equation of hyperbola C1 is obtained

The equation of hyperbola C1 is set as: y ^ 2 / 4-x ^ 2 / 9 = a, which can be solved by substituting m (9 / 2, - 1), so it is very simple. The methods of this topic are all like this, because they are relatively simple and easy to understand
