Prove that for any real number x > 0,
Question 8: For any integer n 20 and any real number x with 0<<1, define the function (Using the ratio test from calculus, it can be shown that this infinite series converges for any fixed integer n.) Determine a closed form expression for Fo(x). (You may use any result that was proven in class.) Let n 21 be an integer and let r be a real number with 0<< 1. Prove that 'n-1(2), n where 1 denotes the derivative of...
Exercise 6 requires using Exercises 4 and 5.
Exercise 4. Let a be any real number. Prove that the Euclidean translation Ta given by Ta(x, y)(a, y) is a hyperbolic rigid motion. *Exercise 5. Let a be a positive real number. Prove that the transformation fa: HH given by fa(x, y) (ax, ay) is a hyperbolic rigid motion Exercise 6. Prove that given any two points P and Q in H, there exists a hyperbolic rigid motion f with f(P)...
Prove that for any two real numbers x and y, |x + y| ≤ |x| + |y|. Hint: Use the previously proven facts that for any real number a, |a|≥ a and |a|≥−a. You should need only two cases.
7. Prove that for any positive real number r, if r is not an integer, then [x]+-1= 1
(b) Uniqueness of multiplicative inverse. Prove: If y E R is any real number with the property that ry 1 and yx1 for all E R with 0, then y 1/x
use all 3 cases please
0. Prove that for every real number x, if -3| > 3 then x2 > 6x. Proof: Given |x - 3]> 3.
Suppose a is a real number and 1 + a > 0. Prove that (1 + a)" > 1+ na for every integer n > 1.
We write R+ for the set of positive real numbers. For any positive real number e, we write (-6, 6) = {x a real number : -e < x <e}. Prove that the intersection of all such intervals is the set containing zero, n (-e, e) = {0} EER+
