Finding Z f(g(x))g′(x)dx by substituting u = g(x) Example Suppose now we wish to find the integral Z 2x √ 1+x2 dx (3) In this example we make the substitution u = 1+x2, in order to simplify the square-root term. We shall see that the rest of the integrand, 2xdx, will be taken care of automatically in the

(b) 0 ≤ sin2(x) ≤ 1 for all x, so 0 ≤ sin2(x) x 2 ≤ 1 x for all x≥ 1. Since R∞ 1 1 x2 dx converges (by p-test), so does R∞ 1 sin2 ...

Therefore, by de nition, Z 1 0 x 2 p 1 x2 dx= lim b!1 Z b 0 x p 1 x2 dx: Make the substitution x= sin . Then dx= cos d . Also, when 0 = x= sin we have that = 0, and when b= x= sin we have that = arcsin(b). Hence, the above limit is ...
