Question 3640 true or false if x is positive and y = x, then x^2y>0 )true or false If x is positive and y = x, then x is positive ) true or false If x and y are both integers, then /xy/=/x//y/ Answer by robertb(5798) (Show Source) You can put this solution on YOUR website!Exam 2 Sample SOLUTIONS 1 True or False, and explain (a) There exists a function fwith continuous second partial derivatives such that f x(x;y) = x y2 f y= x y2 SOLUTION False If the function has continuous second partial derivatives, then Clairaut's Theorem would apply (and f xy= f yx) However, in this caseYou choose (this y cannot depend on x, it should be any value y) P(x,y) is true Example ∃x∀y,x y = 0 This is not true, because you can always find some y that makes it false However, the proposition ∃x∀y(y 6= 0) , x y = 0 is true 8 additive inverse of x is −x (so that adding them up you get 0) 9 multiplicative inverse of x is 1 x
