PLEASE use smallest counterexample! n(n+1) 1. Prove by smallest counterexample: 1 + 2 + . ....
Prove or find a counterexample for the following. Assume that f (n) and g (n) are monotonically increasing functions that are always larger than 1. f (n) = o (g (n)) rightarrow log (f (n)) = o (log (g (n))) f (n) = O (g (n)) rightarrow log (f (n)) = O (log (g (n))) f (n) = o (g (n)) rightarrow 2^f (n) = o (2^g (n)) f (n) = O (g (n)) rightarrow 2^f (n) = O (2^g...
If true, prove. If false provide counterexample. Let In be a sequence of nested unbounded open intervals. Then In 0. n=1
1 Prove the following using the definitions of the notations, or disprove with a specific counterexample: Theta(g(n)) = O(g(n)) Ohm(g(n)) Theta(alpha g(n) = Theta(g(n)), alpha > 0 If f(n) O(g(n)), then g(n) Ohm(f(n)). For any two non-negative functions f(n) and g(n), either f(n) Ohm(g(n)), or f(n) < O(g(n))
1. Prove with a direct proof or disprove by counterexample. If x is an odd integer, then x3 is an odd integer.
Prove or give a counterexample to the following statement: If the coefficient matrix of a system of m linear equations in n unknowns has rank m, then the system has a solution.
Help please! Using matlab Prove or give a counterexample: if f: X rightarrow Y and g: Y rightarrow X are functions such that g o f = I_X and f o g = I_Y, then f and g are both one-to-one and onto and g = f^-1.
