The integral of 1/(x^2 + z^2)^(3/2) dx can be effectively solved using the substitution x = z*tan(u), which leads to dx = z*sec(u)^2*du. This method simplifies the integral into a more manageable form, allowing for the application of trigonometric identities. An alternative substitution, x = z*sinh(t), is also valid and may yield similar results. Both approaches leverage the properties of trigonometric and hyperbolic functions to facilitate the integration process.
