2012년 1월 22일 (일) 17:59 판

[1]의 회전으로 얻어지는 곡면 [2]

\(\mathbf{x}(u,v)=(\cos (u) \text{sech}(v),\sin (u) \text{sech}(v),v-\tanh (v))\)

\(E=\text{sech}^2(v)\), \(F=0\),\(G=\tanh ^2(v)\)
크리스토펠 기호
\(\begin{array}{ll} \Gamma _{11}^1 & 0 \\ \Gamma _{12}^1 & -\tanh (v) \\ \Gamma _{21}^1 & -\tanh (v) \\ \Gamma _{22}^1 & 0 \\ \Gamma _{11}^2 & \text{csch}(v) \text{sech}(v) \\ \Gamma _{12}^2 & 0 \\ \Gamma _{21}^2 & 0 \\ \Gamma _{22}^2 & \text{csch}(v) \text{sech}(v) \end{array}\)
