1/xlnx Use the chain rule: ln(ln(x)) The derivative of the outside is1/ln(x) times the derivative of the inside. Simple, and easy to understand, so don`t hesitate to use it as a solution of your homework.
Learn more Accept. Thanks. This result can be obtained by using the product rule and the well-known results d(ln(x))/dx = 1/x and dx/dx = 1.
When the first derivative of a function is zero at point x 0.. f '(x 0) = 0. Also from the facts, the derivative of ln (x) is 1/ x, so g ' (x) = 1/ x. The Organic Chemistry Tutor 283,355 views 39:40 d/dx cos(f(x)) = f'(x) * -sin(f(x), the standard way to differentiate cos. Use the product rule on f to find its derivative: f'(x) = d/dx(x) * lnx + d/dx(lnx) * x = lnx + 1. Derivative examples Example #1. f (x) = x 3 +5x 2 +x+8. Then the second derivative at point x 0, f''(x 0), can indicate the type of that point: The derivative of the logarithmic function y = ln x is given by: `d/(dx)(ln\ x)=1/x` You will see it written in a few other ways as well. Free derivative calculator - differentiate functions with all the steps. Write f(x) = xlnx then the derivative of cos(f(x)) is what you are looking for. Simple step by step solution, to learn.

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. The derivative of y = xln(x) with respect to x is dy/dx = ln(x) + 1. So the derivative is just-(lnx + 1)*sin(xlnx), not so scary after all. 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. Company profile for Xilinx Inc. including key executives, insider trading, ownership, revenue and average growth rates. When applying the chain rule: f ' (x) = cos(3x 2) ⋅ [3x 2]' = cos(3x 2) ⋅ 6x Second derivative test. The following are equivalent: `d/(dx)log_ex=1/x` If y = ln x, then `(dy)/(dx)=1/x` We now show where the formula for the derivative of `log_e … This website uses cookies to ensure you get the best experience. Is this correct? 1/[x*ln(x)] The answer to the original problem (find the intervals on which f(x) in increasing and decreasing of the following equation 2x - xlnx) has e in it, which I don't understand.
I would think that it is x(1/x) + 1(lnx). Type in any function derivative to get the solution, steps and graph . View detailed XLNX description & address.
