Hello, Originally Posted by Isomorphism WE have to prove But this is false, because we choose a= 1.03, b = -0.47, c = -0.56, a+b+c = 0, but This is false because you can't have a number which is both superior to 2 and inferior to 1 Like in #1, you can't have something that is both greater than -1/2 and smaller than -1.
