F/?y. Just use quotient rule.?f/? X = ( (4x + 2y)(4) - (4x - 2y)(4) ) / (4x+2y)^2 = (16y) / (4x+2y)^2?
F/? Y = ( (4x + 2y)(-2) - (4x - 2y)(2) ) / (4x+2y)^2 = (-16x) / (4x+2y)^2.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
