Differentiating lnx/x
WebThe derivative of ln 2 x, that is, (lnx) 2 is calculated using the chain rule formula. We have d(ln 2 x) / dx = 2lnx × (1/x) = (2 ln x)/x. Therefore the derivative of ln^2x is equal to (2 ln … Webderivative of lnx; derivative of sec^2; second derivative of sin^2; derivative of arctanx at x=0; differentiate (x^2 y)/(y^2 x) wrt x; View more examples » Access instant learning tools.

WebAug 6, 2024 · The derivative of x is 1, so g ' ( x) = 1. Great! We have all our parts. Now let's plug them into the quotient rule and find the derivative of ln ( x) / x. We see that the … WebJun 28, 2015 · 29. The simplest way is to use the inverse function theorem for derivatives: If f is a bijection from an interval I onto an interval J = f(I), which has a derivative at x ∈ I, and if f ′ (x) ≠ 0, then f − 1: J → I has a derivative at y = f(x), and (f − 1) ′ (y) = 1 f ′ (x) = 1 f ′ (f − 1(y)). As (ex) ′ = ex ≠ 0 for all x ...
