Derivative of y=xlnx-xFor the first team we need to use the product rule Building on this, integral of 1/ (xlnx) - Answer | Math Problem Solver - Cymath. Find the interval (s) where f (x)=lnx/x is decreasing - Wyzant. A function is decreasing on an interval I if its first derivative is less than 0 on that interval.

f (x) = lnx / x We can use the quotient rule to find the first derivative. This perspective suggests that, f' (x) = [x/x - lnx]/x 2 < 0 [1 - lnx]/x 2 < 0 x 2 is always positive. We can cross multiply it to multiply it by zero and eliminate it.

1 - lnx < 0 -lnx < -1 Multiply by -1 and flip the inequality. lnx > 1 Exponentiate ... find dy/dx where y=2^ (x/lnx) | Wyzant Ask An Expert. The chain rule basically states that you need to take the derivative of the outside function and multiply it by the derivative of the inside function: f' (g (x))*g' (x). So we need to establish what the outside function is.

The outside function for this equation is f (x) = 2^x, and the inside function is g (x) = x/lnx. \"GetChoose Topic Examples " (x+1)/2+4=7" "factor x^2+5x+6" "integrate cos (x)^3" More » Calculus Derivative: Quotient Rule - Problems | Derivative: Quotient ....

Quotient Rule for Derivatives - Introduction If you are looking for the derivative of a function, sometimes you might not know where to start. Fortunately, for most functions, there are a set of rules that you can apply to lead to the solution. We will now discuss the case where the expression is a fraction, with one sub-expression in the numerator and another in the denominator.

Let f ( x ) = ( ln x ) 2 , f ' (e^4) | Wyzant Ask An Expert. I'm assuming here that you were looking for f (x)= (ln (x)) 2. To take the derivative, I'll rewrite this so that it looks nicer and we can use the product rule f (x)= (ln (x)) (ln (x)) To restate, the product rule for taking the derivative of a function which is the product of two functions, f*g, is if y = f*g, then y'=f' * g + g' * f f=ln (x) f'=1/x g=ln (x) g'=1/x so f * g' = ln (x)/x, f ...
