Conceptual problem with integration by parts.

Click For Summary
SUMMARY

The forum discussion centers on the conceptual challenges associated with the integration by parts technique in calculus. Specifically, the user questions why only half of the function is obtained when differentiating the product of two functions, f(x) and g(x). The discussion highlights the confusion surrounding the application of the integration by parts formula, which is expressed as ∫u dv = uv - ∫v du. This indicates a need for clarity on the derivation and application of this fundamental calculus concept.

PREREQUISITES
  • Understanding of basic calculus concepts, including differentiation and integration.
  • Familiarity with the integration by parts formula: ∫u dv = uv - ∫v du.

Why is it that whenever we encounter a question which can be solved by integration by parts, we get half the function?

I mean, suppose a differentiated f(x)g(x) yielded [tex]{f'(x) g(x)dx + f(x)g'(x)dx}[/tex], then why do we get only [tex]{f'(x) g(x)dx}[/tex] to extract the original function (f(x)g(x)) from?
