Differentiating loga x is easy and can be done using first principles. Assuming it is a log function to the base number a.d / dx loga x = 1 / xln aThe derivative of loga x is therefore 1 / xln aThis Article Continues...DifferentiationDifferentiation Chain Rule...
Mean, standard deviation, median, percent change in mean, percent change in median, and log rank p value were calculated using R 2.6.2. Analysis of mortality rate was performed using the WinModest statistical package [34]. The best fit model was determined by the "Model Comparison" option ...
2C-D). Marker genes of the new PTC clusters were identified using differential gene expression (DGE) analysis. For DGE analysis, we used the FindMarker command. Significance was defined as a gene with an adjusted p value < 0.05, a ≧ 0.25 average log2-fold difference between the...
x l o ga Law 3: loga(xr)=rlogax To work these examples requires the use of various differentiation rules. If you are not familiar with a rule go to the associated topic for a review. y=x2+33(x−1)4 Step 1: Take the natural log of both sides of the equation and use the la...

用implicit differentiation求得:y’ = 1/cos y 精彩部分:进一步转化为:y’ = 1/√[1-(sin y)^2] 而sin y = x,因此,(sin y)^2 = x^2, 解出:y’ = 1/√(1-x^2) 书本内容: 第一,书本对反函数进行了进一步的解释(补充高中知识欠缺的我)。 Theorem 5.6 Reflective property of inverse functi...
A total of 1,838 potential candidate genes were obtained by considering a less-stringent threshold (-log10 p > 6) and 卤100 kb regions surrounding the significant genomic loci. Moreover, 31 candidate genes were identified through a comprehensive analysis of significant GWAS ...
Dysfunction of pancreatic δ cells contributes to the etiology of diabetes. Despite their important role, human δ cells are scarce, limiting physiological studies and drug discovery targeting δ cells. To date, no directed δ-cell differentiation method has been established. Here, we demonstrate that...
A technique often helpful in computing the derivatives of a differentiable function ƒ(x); setg(x) = log ƒ(x) where ƒ(x) ≠ 0, theng′(x) = ƒ′(x)/ ƒ(x), and if there is some other way to findg′(x), then one also finds ƒ′(x). ...
