This calculus video explains how to find the derivative of x^x^x using a technique called logarithmic differentiation which is useful for differentiating exp The derivative of x^(lnx) is (2*y*(lnx)*(x^(lnx)))/x let y =x^(lnx) There are no rules that we can apply to easily differentiate this equation, so we just have to mess with it until we find an answer If we take the natural log of both sides, we are changing the equation We can do this as long as we take into account that this will be a completely new equation lny=ln(x^(lnx))To find the derivative of y=a^x, we use the exact same steps as that used for differentiating y=e^x, and y=x^x as well Hence, if you did those earlier you should be able to do this one Just as before, you take the log on both sides This brings the x down from
We can solve that for y ′ to get y ′ = y / x − log y x / y − log x You can see that along the line y = x that will simplify to y ′ = 1 as it should Note that the point ( 4, 2) is a solution to the original equation The derivative there isFinding 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) 1Get stepbystep solutions from expert tutors as fast as 1530 minutes Your first 5 questions are on us!
The derivative of y = x 2 is 2x Therefore at a) x = 4, the slope of the tangent is 8 b) The equation of a straight line has this form y = ax b, where a is the slope of the line Therefore, since a = 8, the equation is y = 8x b To find the value of b, we can now proceed as in Solution 1 to Problem 1 in Lesson 34 of Algebra How do you find the derivative of #y=a^x#?Free derivative calculator differentiate functions with all the steps Type in any function derivative to get the solution, steps and graph

Explanation The answer is y' = 1 ⋅ lnx x ⋅ 1 x = lnx 1 This is because the theorem of derivative of product (Product Rule) says y = f (x) ⋅ g(x) ⇒ y'(x) = f '(x) ⋅ g(x) f (x) ⋅ g'(x) where f (x) = x f '(x) = 1 g(x) = lnx g'(x) = 1 x Answer linkA bit of a classic implicit differentiation problem is the problem why I don't want to write it that thick y is equal to X to the X and then to find out what the derivative of Y is with respect to X and people look at that oh I have X to it you know I don't have just a constant exponent here so I can't just use the power rules how do you do it and the trick here is really just to take the In calculus, the differential represents the principal part of the change in a function y = f(x) with respect to changes in the independent variableThe differential dy is defined by = ′ (), where ′ is the derivative of f with respect to x, and dx is an additional real variable (so that dy is a function of x and dx)The notation is such that the equation

Derivative is the important tool in calculus to find an infinitesimal rate of change of a function with respect to its one of the independent variable The process of calculating a derivative is called differentiation Follow the rules mentioned in the above derivative calculator and understand the concept for deriving the given function toFirst, let us consider the derivative (with respect to x) of xˣ (which I will write as x^x) Let y = x^x Then y = e^ln (x)^x = e^ ln (x)*x, where e is the base of natural logarithms Let u = ln (x)*xDerivative by first principle refers to using algebra to find a general expression for the slope of a curve It is also known as the delta method The derivative is a measure of the instantaneous rate of change, which is equal to f ′ ( x) = lim h → 0 f ( x h) − f ( x) h f' (x) = \lim_ {h \rightarrow 0 } \frac { f (xh) f (x
