x = a secn θ అయితే, y = b tann θ, అప్పుడు:
1
\({\left( {\frac{a}{x}} \right)^{2/n}} + {\left( {\frac{b}{y}} \right)^{\frac{2}{n}}}\)=1
2
\({\left( {\frac{x}{a}} \right)^{2/n}} - {\left( {\frac{y}{b}} \right)^{\frac{2}{n}}}\)=1
3
\({\left( {\frac{a}{x}} \right)^{2/n}} - {\left( {\frac{b}{y}} \right)^{\frac{2}{n}}}\)=1
4
\({\left( {\frac{x}{a}} \right)^{2/n}} + {\left( {\frac{y}{b}} \right)^{\frac{2}{n}}}\)=1
