Proof: Integral ln(x) - Math.com
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
What is the integration of ln x? Maths Q&A - BYJU'S
∫ ln x d x = ∫ ln x. 1 d x ⇒ ∫ ln x d x = ln x. x-∫ x 1 x d x + C ∵ C is a constant. ⇒ ∫ ln x d x = x ln x-x + C Hence, the required integral is ∫ ln x = x ln x - x + C ,where C is a constant.
7.1: The Logarithm Defined as an Integral
lnx = ∫x 11 t dt. For x> 1, this is just the area under the curve y = 1 t from to . so in this case it is the negative of the area under the curve from to (see the following figure). Figure : (a) When , the natural logarithm is the area under the curve from to . (b) When , the natural logarithm is the negative of the area under the curve from to .

Understand the mathematics of continuous change. The derivative of the logarithm \ln x lnx is \frac {1} {x} x1, but what is the antiderivative? This turns out to be a little trickier, and has to be done using a clever integration by parts.
Integral of ln(x) (Natural Logarithm) | Detailed Lesson - Voovers
The indefinite integral of ln(x) is given as: ∫ ln(x)dx = xln(x) – x + C. The constant of integration C is shown because it is the indefinite integral. If taking the definite integral of ln(x), you don't need the C. There is no integral rule or shortcut that directly gets us to the integral of ln(x). When finding the definite or indefinite ...
