Introduction to Analysis. Please write neatly so that I may understand your writing thanks. 4. (10 points) Prove that two real numbers a, b satisfy a<b for every e > 0, a <b+€
QUESTION 10 15 points Save Answer Prove the statement by contraposition. For all nonzero real number n. if n is irrational, then its reciprocal 1/n is irrational. [Definition: Reciprocal is one of a pair of numbers that, when multiplieci together, equal 1. For example, reciprocal of k is 1/k, where k is not zero]
18. (a) Let a,..., a, and by,...,b be real numbers. Prove the Schwarz inequality. That is, a6<(2)" (**)". [Hint: For any real numbers & and B, LT-1 (Qa; - Bb;)? > 0. Expand this and choose a and B judiciously.] (b) When does equality hold in the Schwarz inequality?
please prove 9.6 and 9.7 The next three theorems formalize what you may have discovered in the preceding group of questions. 9.6 Theorem. Let K be a positive integer Then, among any k real num- bers, there is a pair of them whose difference is within 1/K of being an integer When we take our collection of real numbers to be multiples of an ir- rational number, then we can find good rational approximations for the irrational number. Remember how...
Please help answer all parts! (1) Prove that 75 is irrational. (State the Lemma that you will need in the proof. You do not need to prove the lemma.) (2) Disprove: The product of any rational number and any irrational number is irrational. (3) Fix the following statement so that it is true and prove it: The product of any rational number and any irrational number is irrational. (4) Prove that there is not a smallest real number greater than...

Please answer question #1 and write legibly. EEM is explicit euler method and IEM is implicit euler method 1. We defined the Theta method: for 0 € [0, 1] Jtq+1 =t, + ; yn+1 = Yn + hof (tr; yn) + (1 - 0)f(tn+1 Yn+1)] Clearly, 0 - corresponds to the Trapezoidal rule, 0 = 1 to EEM, and 0 - o to IEM. Prove that the order of consistency of the Theta method is 1 for any
6) If E is any countable subset of real numbers prove that A*(E) = A*(E) = 0. 7) Show that the set of all real numbers IR is measurable with >(IR) = . 8) Prove that If f : [a, b] IR is continuous [a; b]then it is measurable [a, b]. 9) Give an example of a function f : [O, 1] IR which is measurable on [O, 1] but not continuos on [O, 1]. 10) Find the Lebesgue integral...
Please answer question #1 and write legibly - I have also equation 4.6 from the textbook. Thanks 1. In class, we derived the Central Difference formula for f'(x0) as f'(x) = f(xo + h) – f(20 - h) +002). f'(o)= 2h A similar result, where four points are involved and the error is (h"), is given in the textbook, page 176, Equation (4.6). Prove it. Five-Point Midpoint Formula • f'(xo) = [f(xo – 2h) – 8f (xo – h) +8f...
