(y^2)/8-(x^2)/5 =1

解

\frac{y ^{2}}{8} - \frac{x ^{2}}{5} = 1

(h, k) = (0, 0), a = 22, b = 5

解答ステップ

\frac{y ^{2}}{8} - \frac{x ^{2}}{5} = 1

\frac{y ^{2}}{8} - \frac{x ^{2}}{5} = 1

を標準的な双曲線のequationで書き換える

\frac{( y - 0 ) ^{2}}{( 2 2 ) ^{2}} - \frac{( x - 0 ) ^{2}}{( 5 ) ^{2}} = 1

ゆえに双曲線の特性は:

(h, k) = (0, 0), a = 22, b = 5
