True /False 13. _There is only one copy of the class's member func- tions and that copy is shared among all the class's objects 14. Putting class definition in a separate file (e-g. head- er) makes it easy to reuse. 15. _A private data member of a class can usually be accessed from outside the class. 16. A member function of a class can call other private member functions of the same class. 17. _A destructor function can have parameters....
4. True or False. Label each of the following statements as true or false. If true, give a proof, if false, give a counterexample. (a) Every nontrivial subgroup of Q* contains some positive and some negative numbers (b) Let G be a finite group. Let a E G. If o(a) 5, then o(a1) 5. (c) Let G be a group and H a normal subgroup of G. If G is cyclic, then G/H is also cyclic. (d) Le t R...
1. Let ơ E Aut(R), where R denotes the field of real numbers. a) Prove that if a > b then σ(a) > σ(b) ( . (b) Prove that o is a continuous function. (c) Prove that ơ must be the identity function. Therefore Aut(R)-(1). (see problem 7 on pg. 567 for more details for each step). 1. Let ơ E Aut(R), where R denotes the field of real numbers. a) Prove that if a > b then σ(a) >...
True or False: If f(x) and g(x) are two differentiable functions on an interval (a,b), and f(x)>g(x) on (a,b), then f'(x)>g'(x).
