the truth table of X->Y is
X Y X->Y
T T T
T F F
F T T
F F F
which means X->Y is always true except when X is true and Y is false
we have to show that P(0) is true
let X= n>1 and Y= n2>n
given P(0) which means n=0
so X= False
if we see the table if X is false X->Y is always true so P(0) is true

Let P(n) be some propositional function. In order to prove P(n) is true for all positive integers, n, using mathematical induction, which of the following must be proven? OP(K), where k is an arbitrary integer with k >= 1 If P(k) is true, then P(k+1) is true, where k is an arbitrary integer with k >= 1 P(O) P(k+1), where k is an arbitrary integer with k>= 1

This assignment asks you to prove the following Proposition 1 Let {n} and {n} are two sequences of real numbers and L is a number such that (1.a) un → 0, and (1.b) V EN, -L Swn. We illustrate the proposition. To begin, one can check from the definition that 1/n 0. This fact, plus the arithinetic rules of convergence, generate a large family of sequences known to converge to 0. For example, 11n +7 1 11 +7 3n2 -...

Prove the proposition given in a) with induction or by picture. a) If D(N) satisfies D(N) = 2 D(N/2)+N for N > 1, with D(1) = 0, then D(N)=Nlog N. Where D(N) is the number of operations required to solve the problem of size N. b) Also, assume an example where N = 1000000 (i.e. 10^6) is problem size.

2. Determine if the proposition below is true or false. Justify all your conclusions. If a biconditional statement is found to be false, you should clearly determine if one of the conditional statements within it is true. In that case, you should state an appropriate theorem for this conditional statement and prove it. Proposition 1. For all integers m and n, 4 divides (m2 – n) if and only if m and n are both even or m and n...
