Setting log x = t, we can rewrite the integral as which by the formula for integration of e x [f(x)+f’(x)] is simply e x f(x) and hence is e t / 1+t i.e. x/(1+log x)
We can reduce the effort substantially...... This is easy to integrate
if x is positive, then f(x) becomes = > x^2 – 1 now this a parabola upwards with -1 as intercept. find the intersection points for gx and fx and tgen plot it on the graph. then integerate them from...
