How Is the Integral of Natural Log of x Calculated?

Click For Summary
SUMMARY

The integral of the natural logarithm of x, denoted as ∫ln(x)dx, is calculated using integration by parts. The anti-derivative is expressed as x(ln x - 1). This method involves selecting u = ln(x) and dv = dx, leading to the derivation of the result through the application of the integration by parts formula.

The anti-derivative of the natural log of x is x(ln x -1). This can be seen by integrating the natural log through integration by parts, letting dv=dx and u= ln x.

Btw, welcome to Physicsforums!
