I need help with my discrete math question. thanks in advance Let f(x) = 0 + 0,-1-1...+ar+ao with 00, 01,..., an being real numbers. Prove that f(0) E O(") by finding a pair of witnesses C and k such that f(x) < Cx" whenever I k.
Please help me solve these discrete math problems. Please show work so that i may follow and understand. Problem 4. Let r, y be nonzero integers and let n be a positive integer. Prove the following by induction Hint: Consider problem (1d) where r = . y
I am need help with this math problem, is there anyone can help me to solve it, with step pls so that I am able to learn how to do it by myself next time r2 secdx r2 secdx
Wow.. I spend 5hous to understand these problems but cant.. anyone help me? Can anyone solve these question and explain why the answer is open or closed or connected or interior boundary? I have all the answers but I dont understand why.. it is open.. so can anyone explain WHY? Thx!! For each of the sets in Exercises 1 to 8, (a) describe the interior and the boundary, (b) state whether the set is open or closed or neither open...
I need help with my discrete math problem. can you show me step by step process . Thanks in advance 3. Give a big-O estimate and a pair of witnesses for the number additions used in this segment of an algorithm. t:= 0 for i:=1 ton for j := 1 to n-i t:=t+i+j
Discrete Math I'm confused with the questions listed below. Can you please solve and explain in detail? how it transforms one to the other to get the answer? Using propositional logic properties and other logical equivalences (not truth tables), prove the following statements: 1. (p Vq) V (p V -q) is a tautology 2. ((p-+ r) Л (q r) Л (pv q)) _+ r is a tautology 3. (pVq) Л (-р Л q) is a contradiction 4. (1-p) Λ (p...
need help with proving discrete math HW, please try write clearly and i will give a thumb up thanks!! Let A and be B be sets and let f:A B be a function. Define C Ax A by r~y if and only if f(x)f(y). Prove thatis an equivalence relation on A. Let X be the set of~-equivalence classes of A. L.e. Define g : X->B by g(x) Prove that g is a function. Prove that g is injective. Since g...
SOS!!!! Anyone can help me solve this problem?
Discrete Math: Prove that there can be no perfect square between 25 and 36, i.e. there is no integer n so that 25 < n2 < 36. Prove this by directly proving the negation. Your proof must only use integers, inequalities and elementary logic. You may use that inequalities are prsered by adding a number on both sides, or by multiplying both sides by a positive number. You cannot use the square root function. Do not write a proof by...
Can anyone help me with this Linear Algebra question? dy =1 +1 dt X-- Solve the system: 5.) dx dy 2y=e + dt d
