For each of the following pairs of statements, determine whether two statements are equivalent or not. 1. For all integers x>20, for all integers y>30, sin(x) * cos(y) > 1/(xy). For all integers y>30, for all integers x>20, sin(x) * cos(y) > 1/(xy). 2. There exists an integer x>0 so that for all integers y>0, we have xy=2y. For all integers y>0, there exists an integer x>0 so that xy=2y.
