when we do partial derivatives we use the curly ∂ to represent a partial change in something w/ respect to a partial change in something else. but say we have an integral with the integrand as a function of (x,y). why do we not use the curly ∂ as the differential when we integrate?(adsbygoogle = window.adsbygoogle || []).push({});

example..

why is it proper to write

∫2xydx

as opposed to this?

∫2xy∂x
