Introduction to Derivative of ln6x

Derivatives have a wide range of applications in almost every field of engineering and science. The derivative of ln(6x) can be calculated by following the rules of differentiation. Or, we can directly find the derivative ln 6x by applying the first principle of differentiation. In this article, you will learn what the ln 6x derivative is and how to calculate the ln6x derivative by using different approaches.

What is the derivative of ln 6x?

The derivative of ln x with respect to x is a fundamental concept in calculus, and it's essential to understand how to compute it. It can be denoted as d/dx [ln(6x)], and it tells us the rate of change of the natural logarithmic function ln x. In other words, it shows us how quickly the value of ln(6x) is changing concerning changes in the variable x. This derivative can be simplified as 1/ x, indicating that the derivative of ln6 is always a fraction with x in the denominator. It's important to note that ln(6x) represents the logarithm of 6x with base e, which is a critical detail for solving various calculus problems.

Derivative of ln6x formula

The formula for the derivative of ln(6x) is equal to 1/x and mathematically it can be written as:

d/dx(ln(6x)) = 1/x

This formula tells us how the function ln 6x changes with a change in its variable x. This is an essential formula to know in calculus, as it allows us to solve various problems involving logarithmic functions. 

How do you prove the derivative of ln 6x?

There are multiple derivative rules to derive the ln6x derivative, and different methods may be more useful depending on the problem at hand. Some of the most common techniques to prove the ln(6x) derivative are:

  1. First Principle
  2. Implicit Differentiation
  3. Product Rule

Each method provides a different way to compute the ln(6x) differentiation. By using these methods, we can mathematically prove the formula for finding the ln6x derivative.

Differentiation of ln(6x) by first principle

According to the first principle of derivative, the ln 6x derivative is equal to 1/x. The derivative of a function by first principle refers to finding a general expression for the slope of a curve by using algebra. 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 f(x+h)-f(x) / h

This formula allows us to determine the rate of change of a function at a specific point by using limit definition of derivative.

Proof of ln(6x) derivative by first principle

To prove the derivative of ln(6x) by using first principle, we start by replacing f(x) by ln x.


By logarithmic properties,

f(x)=lim {ln(x+h/x)/h}


f(x)=lim {ln(1+h/x)/h}

Suppose t=h / x and h=xt. When h approaches zero, t will also approach zero.

f(x)=lim {ln(1+t)/xt}


f(x)=lim ln (1/xt) ln (1+t)

By logarithmic properties, we can write the above equation as,

f(x)=(1/x) lim ln(1+t)^1/t

Hence by limit formula, we know that,

lim ln(1+t)^1/t =ln e =1

Therefore, the derivative of ln6 is;


Derivative of ln6x using implicit differentiation

implicit differentiation is a technique used to find the derivative of a function that is defined implicitly by an equation involving two or more variables. We can use this method to prove the differentiation of ln(6x).

Proof of derivative of ln 6x by implicit differentiation

To prove the derivative of natural log, we can start by writing it as,


Converting in exponential form,

ey = 6x

Applying derivative on both sides,


ey.dy/dx = 6



Since x=ey

Derivative of ln(6x) using product rule

Another method to calculate the differential of ln 2x is the product rule which is a formula used in calculus to calculate the derivative of the product of two functions. Specifically, the product rule is used when you need to differentiate two functions that are multiplied together. The formula for the product rule solver is:

d/dx(uv) = u(dv/dx) + (du/dx)v

In this formula, u and v are functions of x, and du/dx and dv/dx are their respective derivatives with respect to x.

Proof of ln6x differentiation by product rule

The function ln x can be written as;

f(x)= 1. ln(6x)

Applying derivative with respect to x,

f(x)=(1. ln(6x))

Now by using product rule,

f(x)=1.(ln(6x))+ln(6x) (0)




Hence the ln(6x) derivative is always equal to the reciprocal of x.
