Click For Summary
The discussion centers on confusion between integration by parts and partial differentiation. A user initially struggles with a differentiation problem but ultimately arrives at the correct product rule formula for derivatives. They then express that the problem relates more to integration by parts rather than partial differentiation. This highlights a common misunderstanding in calculus concepts. The conversation emphasizes the importance of correctly identifying the mathematical operation required for problem-solving.

$\dfrac{d}{dx}[f(x)h(x)] = f’(x)h(x) + f(x)h’(x)$
$\displaystyle f(x)h(x) = \int f’(x)h(x) \, dx + \int f(x)h’(x) \, dx$
$\displaystyle (x+1)^5 = \sin{x} + \int f(x)h’(x) \, dx$
finish it ...

I think this is a problem on "integration by parts", NOT "partial differentiation".
