Notes |
minuend − subtrahend = difference |
被减数 - 减数 = 差 |
|
arithmetic progression (AP) / arithmetic sequence |
等差数列 |
|
geometric progression (GP) / geometric sequence |
等比数列 |
|
derivative |
导数 |
|
turning point := at which the derivative changes sign |
极值点 := 导数正负分界点(导数为 0 且变号) |
$f’=0$ && $f’(x-\delta) \cdot f’(x+\delta)<0$==单调性发生变化(但$x_0$处不一定可导) |
stationary point / critical point, of a differentiable function := at which the derivative/slope is 0 |
可微函数 的 驻点 := 导数为 0 的点 |
$f’=0$,$x_0$可导是前提. 极值点+可导=驻点 |
saddle point (stationary points that are neither local maxima nor minima) |
鞍点 (既不是最大值,也不是最小值的驻点)(导数为 0,不变号) |
$f’=0$ && $f’(x-\delta) \cdot f’(x+\delta)>0$ |
inflection [point] == flex |
拐点/反曲点,(凹凸分界点) |
$f’’=0$ && $f’’(x-\delta) \cdot f’’(x+\delta)<0$ == 曲率变号 |
concave == convex upward |
凹函数(头向上,两腿向下) |
$f’’>0$ |
convex == concave upward |
凸函数(头向下,两腿向上) |
$f’’<0$ |
