This is correct. Note that ln(ax) = ln(a) + ln(x).

We would like to show you a description here but the site won’t allow us.

f(x) = a˟ then; f ′(x) = ln(a) a˟ f(x) = e˟ then; f ′(x) = e˟ f(x) = aᶢ˟ then f ′(x) = ln(a)aᶢ˟ g′˟ f(x) = eᶢ˟ then f ′(x) = eᶢ˟ g′(x) When you have [math]a\ln{x}[/math] as a rule, you can always rewrite it as [math]\ln{\left(x^a\right)}[/math] In this case, you’ve got [math](-1)\ln{x}[/math] so Finding the derivative of x x depends on knowledge of the natural log function and implicit differentiation. Let y = x x. If you take the natural log of both sides you get. y = x x then ln(y) = ln(x x) = x ln(x) Now differentiate both sides with respect to x, recalling that y is a function of x. 1 / y y' = ln(x) + x 1 / x = ln(x… Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … Get the answer to Derivative of xlnx-x with the Cymath math problem solver - a free math equation solver and math solving app for calculus and algebra. = e ^u (n ln x) (Set u = n ln x) = [e ^(n ln x)] [n/x] = x ^n n/x = n x ^(n-1) Q.E.D.

Derivative of logs with base other than e First, let's look at a graph of the log function with base e, that is: f(x) = loge(x) (usually written " ln x "). The tangent at x = 2 is included on the graph.

Visit Stack Exchange. Loading… 0 +0; Tour Start If y = x x and x > 0 then ln y = ln (x x) Use properties of logarithmic functions to expand the right side of the above equation as follows. ln y = x ln x We now differentiate both sides with respect to x, using chain rule on the left side and the product rule on the right. y '(1 / y) = ln x + x(1 / x) = ln x + 1 , where y ' = dy/dx Multiply both sides by y y ' = (ln x + 1)y Substitute y by x 2015-08-04 2010-01-18 For example, to calculate online the derivative of the difference of the following functions `cos(x)-2x`, enter derivative_calculator(`cos(x)-2x;x`), after calculating result `-sin(x)-2` is returned.

So the derivative of the natural log of x, we can just to go to the basic definition of a derivative. It's equal to the limit as delta x approaches 0 of the natural log of x plus delta x minus the natural log of x. All of that over delta x. Now we can just use the property of logarithms.

Now implicitly take the derivative of both sides with respect to x remembering to multiply by dy/dx on the left hand side since it is given in terms of y not x. e y dy/dx = 1. From the inverse definition, we can substitute x in for e y to get. x dy/dx = 1 . Finally, divide by x to get dy/dx = 1/x. We have proven the following theorem .

Note this result agrees with the plots of tangent lines for both positive and negative x. For x = 2, the derivative is 2/2 = 1, which agrees with the plot. And for x = -2, the derivative is 2/ (-2) = -1, which agrees with the negative sloping tangent line at x = -2. the derivative of any constant to the x power is found like this. start with a^x where a can be any constnat. Use log rules to rewrite a^x as e^ (ln (a^x)) let me know if you don't get how that works.
