Seeing √1 ± x2 is usually a sign to look at trig substitutions or hyperbolic trig substitutions that will let you simplify the square root without making other parts of the integrand worse. In this case, consider x = sinhu. Then x2 + 1 = cosh2u, and dx = coshudu, giving ∫x2√x2 + 1dx = ∫sinh2u√cosh2ucoshudu = ∫sinh2ucosh2udu.

When we defined the definite integral ∫b af(x) dx, we made two stipulations: The interval over which we integrated, [a, b], was a finite interval, and. The function f(x) was continuous on [a, b] (ensuring that the range of f was finite). In this section we consider integrals where one or both of the ... NettetSolution: To find the value of the integral 1 / (1 + x 2 ), we will use the substitution method of integration. Let, I = ∫ 1 / (1 + x 2) dx, Let x = tan θ or θ = tan -1 x. On derivating x with respect to θ, we get. ⇒ dx = sec 2 θ dθ. Substitute the values of x and dx in I,
