For Finding Integration of lnx (log x),

we use Integration by Parts

 

We follow the following steps

  1. Write ∫ log x dx = ∫ (log x) . 1 dx
  2. Take first function as log x, second function as 1.
  3. Use integration by Parts and solve

Example 18 - Find integration log x (lnx) - Integration by parts

There are other formulas which are used to find Integral, refer Integral Table .
