To integrate this, we use a trick, rewrite the integrand (the expression we are integrating) as 1.lnx . We then let v = ln x and du/dx = 1 . Hence ∫ ln x dx = x ln x - ∫ x (1/x) dx = x lnx - ∫ dx = x lnx - x + constant...

The Trapezium Rule is a method of finding the approximate value of an integral between two limits. The area involved is divided up into a number of parallel strips of equal width. Each area is considered to be a trapezium(trapezoid). ...
If the width is narrow enough, each strip can be treated as a trapezium.Suppose the area under the curve is divided into four strips of equal width h; the shape of each strip is nearly a trapezium. So, let's calculate the area of each trapezium....
