使用链式法则求微分,根据该法则,ddx[f(g(x))]ddx[f(g(x))]等于f'(g(x))g'(x)f′(g(x))g′(x),其中f(x)=ln(x)f(x)=ln(x)且g(x)=1+exg(x)=1+ex。 点击获取更多步骤... 要使用链式法则,请将u设为1+ex。 ddu[ln(u)]ddx[1+ex] ...
What the natural logarithm of the e constant (Euler's constant)?ln(e) = ?The natural logarithm of a number x is defined as the base e logarithm of x:ln(x) = loge(x)So the natural logarithm of e is the base e logarithm of e:...
Natural logarithm is the logarithm to the base e of a number. Natural logarithm rules, ln(x) rules.
If successful, log1p() returns the value of the above function ofx. log1p() will fail under the following conditions: Ifxis less than -1.0, log1p() will return -HUGE_VAL and set errno to EDOM. Ifxis equal to -1.0, log1p() will return -HUGE_VAL and set errno to ERANGE. ...

The LN function returns the natural logarithm of a number in Excel. It has one argument only—number. Note: Zero or negative numbers will result in #NUM! error and non-numeric values in the #VALUE! error. Read More: How to Calculate Log in Excel Suppose you have the following dataset....
The chiasma position data were analysed using the log-likelihood ratio statistic (Kullback, 1959). This statistic closely follows the theoretical 2-distribution and has been used to examine homogeneity of chiasma position in relation to population, sex and presence of B-chromosomes. Essentially this...
A clustering is considered perfect when the value of F-measure is 1. Entropy-based measures [15,106,122,123]. It measures the homogeinity (the class distribution intracluster should be assigned to a single class) and completeness (it is symmetrical to homogeinety, i.e., all points member...
