Derivative of ln of u
WebSolution: We can calculate the antiderivative of ln x by x using the substitution method. To evaluate the antiderivative, we will use the formula for the derivative of ln x which is d (ln x)/dx = 1/x. For ∫ (1/x) ln x dx, assume ln x = u ⇒ (1/x) dx = du. Therefore, we have ∫ (1/x) ln x dx = ∫u du = u 2 /2 + C = (ln x) 2 /2 + C WebOct 14, 2024 · Three examples of the derivative of ln(u) using the chain rule

WebFind the derivative of the function f(x) = 1/x^ Solution: The derivative of 1/x^2 is -2/x^ Find the definite integral of the function f(x) = x^2 + 3x + 2 from x = 0 to x = 1 Solution: The definite integral of x^2 + 3x + 2 from x = 0 to x = 1 can be found using the antiderivative of x^2 + 3x + 2, which is x^3/3 + 3x^2/2 + 2x. WebMay 31, 2016 · Explanation: Taking this derivative requires knowing the chain rule and the fact that the derivative of ln(u) = 1 u. Let u = 5x. This means that du dx = 5. Then it follows that dy dx = d dx ln(u) = 1 u ⋅ du dx = 1 5x ⋅ 5 = 1 x You can easily prove that for all a ∈ R, d dx ln ax = 1 x Answer link

WebAug 14, 2015 · You can actually show that the derivative of ln x is 1 x for all x ≠ 0. For x > 0 this should be clear; for x < 0, we know x = − x, and hence we want to calculate d d x ( ln ( − x)) = 1 − x ( − 1) = 1 x. Once you know that, then you can proceed with the chain rule, as usual. Share Cite Follow answered Aug 14, 2015 at 5:11 Joey Zou
