翻开数学史,我们知道17世纪前半叶,法国数学家笛卡尔和费马分别创立了解析几何.使用的方法是坐标法,而坐标法的实质是距离.1637年,笛卡尔发表了《几何学》,创立了直角坐标系.他用平面上的一点到两条固定直线的距离来确定点的坐标,用坐标来描述空间上的点.距离产生美,确实在几何 Turning over the history of mathematics, we know that the French mathematicians Descartes and Fermat respectively created analytic geometry in the first half of the 17th century. The method used was the coordinate method, and the essence of the coordinate method was the distance. In 1637, Descartes published "Geometry Learn, created the rectangular coordinate system. He uses the distance from the point on the plane to the two fixed lines to determine the coordinates of the point, and the coordinates to describe the points on the space. The distance to produce beauty is indeed in the geometry.
