Finding the integral of ln(x) instructs the process of assimilation by parts. This lesson will show how to find the integral of ln(x) using integration by parts and explain how and why assimilation by parts works.

What Is The Integral Of Inx

Let’s apply these steps to the integral of ln(x). We know our two gatherings are ln(x) and 1. Since the derivative of ln(x) is renowned as 1/x, it would probably be a good idea to let u = ln(x). Similarly, the integral of 1 is well-known as x + C, where C is a constant. Thus, we will let dv = 1dx. It’s important to note that we don’t include the constants when unearthing different integrals during the solving process. This is because the constants that would show up throughout will all be taken care of at the end of the process when we have our final constant.

At this point, we’ve actually completed steps 1 and 2, and we have our u, du, v, and dv.

u = ln(x)

dv = 1dx

du = (1/x)dx

v = x

All we have to do now is plug the results into our formula and simplify.

In this video I determine how to find the indispensable or antiderivative of the natural log of x, ln(x), using integration by parts. You may be speculating, there’s only one part to this integral: ln(x). Well, we can make the ‘u‘ part be ln(x) and the ‘dv’ part be equal to dx.

Proof: the derivative of ln(x) is 1/x. Proving that the by-product of ln(x) is 1/x by using the definition of the derivative as a limit, the hallmarks of logarithms, and the explanation of 𝑒 as a limit.

Strategy

ln(x) dx

set
u = ln(x), dv = dx
then we find
du = (1/x) dx, v = x

substitute

ln(x) dx = u dv

and use integration by parts

= uv – v du

substitute u=ln(x), v=x, and du=(1/x)dx

= ln(x) x – x (1/x) dx
= ln(x) x – dx
= ln(x) x – x + C
= x ln(x) – x + C.

Integral Of 1/Inx

The integral of ln(x) may look simple, but it’s actually a bit involved. To find this integral, we have to use integration by parts. This process is used to find the integral of a product of functions. The formula we use for integration by parts is as follows:

Now you may look at our problem, solve the integral of ln(x), and wonder how this is a product of functions. Well, we can think of the integral of ln(x) as the integral of ln(x)*1. This way, we have a product of the functions f(x) = ln(x) and g(x) = 1.

Okay, now that we’ve cleared that up, let’s look at the steps involved when using integration by parts.

Identify your two functions u and dv. This is usually the hardest step. One thing to help with this step is to keep in mind that we want u to be a function that is easy to find the derivative of, and we want dv to be a function for which it’s easy to find the integral. Put the dx from the original integral with whichever function you named as dv.

Find du, or the derivative of u, and find v, or the integral of dv.

Plug u, v, du, and dv into the integration according to the parts formula and simplify.

Integral Of Inx 2

So we’ve found the integral of ln(x), but the use of integration by parts may be new to you, and it may have left you with some questions. To remedy this, let’s take a closer look at integration by parts.

As we said, integration by parts is used to find the integral of products of functions. We can actually derive the formula for integration by parts from the product rule for derivatives. Let’s see how this is done.

We’ll start with the product formula for derivatives.

Next, we’ll integrate both sides of the function. You may wonder why, but this approach will all become more and more clear as we move along.

What is ln and log?

Usually log(x) means the base 10 logarithm; it can, also be written as log10(x) . … ln(x) means the base e logarithm; it can, also be written as loge(x) . ln(x) tells you what power you must raise e to obtain the number x.
