Derivative of log x Proof by First Principle We will prove that d/dx(logₐ x) = 1/(x ln a) using the first principle (definition of the derivative). Proof: Let us assume thatf(x)=logₐ x.By first principle,the derivative of afunctionf(x)(which is denoted by f'(x)) is gi...
∫lnxdx=∫tde^t=te^t-∫e^tdt=te^t-e^t=xlnx-x 所以∫logaxdx=1/lna*∫lnxdx=（xlnx-x）/lna 导数（Derivative），也叫导函数值。又名微商，是微积分中的重要基础概念。当函数y=f（x）的自变量x在一点x0上产生一个增量Δx时，函数输出值的增量Δy与自变量增量Δx的比值在Δx趋于0...
