Question 1

Find and  if z = f(x, y) = cos (ln(x2 + xy + y2)).
=   ;   =
= - ;   = -
= - ;   = -
= - ;   = -
= - ;   = -

Question 2

Find and  if z = f(x, y) = x2y3 sin(x - 2y).
= 2xy3 sin(x - 2y) + y3 cos(x - 2y),   = 3x2y2 sin(x - 2y) - 2x2 cos(x - 2y)
= 2xy3 cos(x - 2y),   = - 6x2y2 cos(x - 2y)
= 2xy3 sin(x - 2y) - x2y3 cos(x - 2y),   = 3x2y2 sin(x - 2y) + 2x2y3 cos(x - 2y)
= 2xy3 cos(x - 2y),   =  6x2y2 cos(x - 2y)
= 2xy3 sin(x - 2y) + x2y3 cos(x - 2y),   = 3x2y2 sin(x - 2y) - 2x2y3 cos(x - 2y)
