It would be very useful to have a theory about computability of functions R" -> R. Given that there Q.2 are an u...
2. Determine whether the given sets are countable or uncountable. Justify each answer with a bijection (or table like we did with Q+) or using results from class/textbook. (a) {0, 1, 2} * N (b) A = {(x, y) : x2 + y2 = 1} (c) {0, 1} R Che set of all 2-element subsets of N (e) Real numbers with decimal representations consists of all 1s. (f) The set of all functions from {0,1} to N
In this problem we consider only functions defined on the real numbers R. A function f is close to a function g if 3x E R s.t. Vy E R, A function f visits a function g when Vz E R, R s.t. a<y and f() -g) For a given function f and n E N, let us denote by n the following function: n(x)-f(x)+2" Below are three claims. Which ones are true and which ones are false? If a...
4.The (p,q) hypergeometric function is defined as where aj ∈ R, bl ∈ R and for any real value a we have that (a)0 =1 (a)n =a(a + 1)(a + 2)···(a + n − 1), n ≥ 1. So for example, we have that 0F0(;;x) = ex, and if we have the Bessel function Jn(x) where , then we have . Write a program which computes the (p,q) hypergeometric function. It should take as input vectors a and b where...

1. Write R' = {(x, y) |X, Y ER} to represent the set of all 1x2 row vectors of real numbers. This is the standard Euclidean plane you all know and love. If such a row vector is multiplied on the right by a 2x2 matrix, then the output is again in R"; such matrices are called linear transformations. 1. Find a linear transformation that rotates the plane R by a radians. That is, find a matrix T such that...
