17世纪时笛卡儿,费尔玛及其他学者解决曲线的切线问题及变量的极大值和极小值的问题是走向建立微分学最初尝试.各别的这类问题也曾为古希腊数学家解决过.比如,他们发现圆,圆锥曲线和一些别的曲线的切线作法;同时,他们把与曲线相遇但不穿过曲线的直线定义为该曲线的切线(不难看出,这种切线定义是与现在的定义不相符的);培尔加的阿波罗尼(??曾研究过从定点到已知圆锥曲线上之点的最长的和最短的线段问题,等等.但是这些古代数学家所研究出来的解决
In the 17th century, Descartes, Fermat, and other scholars solved the problem of the tangent of the curve and the maximum and minimum values of the variables were the initial attempts to establish differential calculus. Each of these issues was also ancient Greek mathematics. For example, they found tangents to circles, conic curves, and some other curves; at the same time, they defined the line that met the curve but did not cross the curve as the tangent of the curve (it’s easy to see that this tangent definition Is inconsistent with the current definition;) Apolloni of Pergar (?? studied the problem of the longest and shortest line from the fixed point to the point on the known conic, etc. But these ancient mathematics Home Solutions
