Question Number 7937 by tawakalitu last updated on 24/Sep/16

f(x, y) = x^2 siny + cos(x − 2y) Obtain f_(xx) , f_(yy) , f_(xy) , is f(x, y) contineous ?

$${f}\left({x},\:{y}\right)\:=\:{x}^{\mathrm{2}} {siny}\:+\:{cos}\left({x}\:−\:\mathrm{2}{y}\right) \\ $$$${Obtain}\:\:{f}_{{xx}} \:,\:\:{f}_{{yy}} \:,\:\:{f}_{{xy}} \:,\:\:{is}\:\:{f}\left({x},\:{y}\right)\:{contineous}\:? \\ $$
