摘要：利用球面的参数方程和空间平面的四阶行列式方程建立基本模型 ,运用Mathematica数学软件进行公式推导 ,从而得到空间曲线的参数方程及其曲线积分式和近似解 ,对新旧航线作了详细的讨论 ,并用 C语言进行数据搜索 ,得出近似解。从数学上合理地解释了“飞越北极 ,北京到底特律的飞行时间可节省 4h”
By using the parametric equation of the sphere and the four matrices, a basic model was established and inferred with Mathematica software, so the approximation solutions of space curve parametric equation and its curve integral were obtained. The two airlines (the original and the new) were disussed in detail, and C language was used to search the data to get the solution. Our conclusion is that 4 hors can be saved from Beijing to Detroit if you fly to the arcitic pole.
