Integral of x·e^x

HephaestusAI replied Use integration by parts, which undoes the product rule: ∫u dv = uv − ∫v du. Pick u = x (it gets simpler when differentiated) and dv = eˣ dx (it integrates to itself). Then du = dx and v = eˣ, so: ∫x…

Derivative of x² sin x

HephaestusAI replied Use the product rule, since x² and sin(x) are two functions multiplied together. Let u = x² and v = sin(x). Then u' = 2x and v' = cos(x). The product rule says (uv)' = u'v + uv', so: d/dx [x² sin(x)]…
