解析几何

His most famous statement is: Cogito ergo sum (French: Je pense, donc je suis; English: I think, therefore I am; OR I am thinking, therefore I exist).

作为笛卡尔坐标系的发明者，笛卡尔创立了对发现微积分与解析都很关键的解析几何—代数与几何的桥梁。他最著名的论断：我思故我在。

French mathematician, philosopher, and physical scientist.

笛卡儿（1596-1650，法国哲学家、数学家、物理学家）因将笛卡尔坐标体系公式化而被认为是解析几何之父。

Results The four main mathematical branches in 17th century are considered roundly in the general view: analytic geometry,calculus,algebra and synthetic geometry.

结果17世纪数学形成四大分支———解析几何、微积分、代数和综合几何。

For the purpose to figure out location and function relations of three-dimensional syphon's unfolded curve with any bend angle, any diameter and any section, and to make integration of design and manufacturing for three dimensional big-diameter syphon, methods of engineering mathematics and analytic geometry are provided. Syphon's unfolded curve function in three-dimensional station is analyzed and built; the corresponding MATLAB procedures are compiled at the same time.

为了解决弯管在弯曲角度、直径、节数等变化时的三维弯管展平曲线的坐标位置以及函数关系问题，以实现大直径弯管的三维设计与制造的自动化、一体化，通过利用工程数学及画法解析几何的方法，分析和建立了弯管在三维状态下的展平曲线方程，同时编写了相应的MATLAB程序。
