∫1x(ln(x))6dx Integration: Integration is defined as the reverse process of differentiation that is used to find the area under any curve or to find the volume of the region bounded by a two-dimensional figure. ∫is a sign of integration. ...
We can also sometimes use integration by parts when we want to integrate a function that cannot be split into the product of two things. The trick we use in such circumstances is to multiply by 1 and take du/dx = 1. Example Find ∫ ln x dx ...
