is this the same? why are they the same? do the order of differential not matter?(adsbygoogle = window.adsbygoogle || []).push({});

d/dx_{i}(dy_{j}/ dx_{j}) = d/dx_{j}(dy_{j}/ dx_{i})

where LHS : differentiate y_{j}w.r.t x_{j}first, then x_{i}

while RHS: differentiate y_{j}w.r.t x_{i}first, then x_{j}

thanks!
