WebAssuming log x is base e, let y = x log x. Take a logarithm of both sides to get log y = log ( x log x) = log x log x. Differentiate both sides to get y ′ y = 2 log x x Multiplying by y gives y ′ = x log x 2 log x x Share Cite Follow answered Oct 11, 2015 at 20:51 Paul Sundheim 2,633 1 15 18 Add a comment You must log in to answer this question.

WebNov 10, 2024 · For x > 0, define the natural logarithm function by. lnx = ∫x 11 t dt. For x > 1, this is just the area under the curve y = 1 t from 1 to x. For x < 1, we have. ∫x 11 t dt = − ∫1 x1 t dt, so in this case it is the negative of the area under the curve from x to 1 (see the following figure). Figure 7.1.1: (a) When x > 1, the natural ...

WebAug 21, 2016 · To find the derivative of log_e (x^2+1)^3 use chain rule. You will often find many cases like expoential, trigonmetric, logarithmic, inverse trigonometric expressions in which you need to use chain rule so can find the derivative so you need to be … WebBasic Idea: the derivative of a logarithmic function is the reciprocal of the stuff inside. Using the properties of logarithms will sometimes make the differentiation process easier. Basic Idea The derivative of a logarithmic function is the reciprocal of the argument. WebFeb 21, 2024 · Using the derivatives of log ( x) formula, we have d d x ( log ( x)) = 1 x ln ( 10) By using chain rule, we get y ′ = 1 x 2 ln ( 10) d d x ( x 2) ⇒ y ′ = 1 x 2 ln ( 10) ⋅ ( 2 x) ⇒ y ′ = 2 x ln ( 10) Hence, the derivative of log ( x 2) is 2 x ln ( 10).
