Determine whether ƒ is a function f om r ℤ to ℝ if r a) ƒ(n) = ∓n By definition, a function must map every point in its domain to a single point in the range Since, for every n, there are two images, n and –n, this is not a function b) ƒ(n) = √(n2 1).

(c) V is the set of functions from R to the positive real numbers that is, V is the set of functions f with domain R such that f(x) > 0 for all x 2R Let f and g be in V We de ne f g and c f by de ning the values these functions take on at any x 2R (f g)(x) = f(x)g(x) (c f)(x) = f(x)c. In N x N, show that the relation defined by (a, b) R (c, d) if and only if a d = b c is an equivalence relation Here (a, b) R (c, d) ⇔ a d = b c (i) Now (a, b) R (a, b) if a, b = b a, which is true ∴ relation R is reflexive (ii) Now (a, b) R (c, d). Question Let f R → R be a smooth function (ie C∞) Suppose that for each t ∈ R there is nt ∈ N such that f(nt)(t) = 0 Prove that there is an interval I of positive length such that the restriction of f to I is a polynomial Proof Define Tn= {t ∈ R f(n)(t).

As the hint suggests, a general line in R2 has the Cartesian equation ax by c = 0, where a and b are not both zero The condition that P 1, P 2, and P 3 all lie on a particular line is precisely that ax i by i c = 0 for each i, or in other words 2 4 x 1 y 1 1 x. Sum of (n/b^n)(xa)^n, b>0 from n=1 to infinity find the radius of convergence and interval of convergence of the series.

However, if you want to formulate the statement $B_d(x,r) = x rB_d(0,1)$ you need a space with an addition and a scalar multiplication Whether the statement is true, depends obviously on the space The usual definition of ball is $$ B_d(x,r) = \{ y \in \mathbb R^n \mid d(x,y) < r \} $$ For $r =0$ the set $B_d(x,r)$ is empty.

Let's say I've got some linear transformation T that is a mapping from RN to RN so if this is its domain which is just RN that is RN and then its codomain is also RN is also R n if you give me some vector in our domain let's call that vector X then T will map it T will map it to some other member of our of RN which is also the co domain so it'll map it over here and we could call that the.

Let's say I have some linear transformation T from r2 to r2 so if that is r2 and then this is r2 t just maps from any member of r2 to another member of r2 just like that and I'm going to define T it's a linear transformation I'm going to define it when I when I take the transformation of some member of r2 it's equivalent to multiplying it by this matrix by the matrix 1 minus 3 minus 1 3 so.

So when ax and bn are broken down into their factors, the only common multiple which is found is 1 When a and b and their factors are removed Continue Reading In ax and bn, the smaller of the 2 is a negative (if ax>bn, b is a negative number and if bn>ax, a is a negative number) Let us assume q is a factor of ax.

Converges uniformly on R to a continuous function Solution 4 Since jcoskxj 1 for all x 2R, we have that coskx k2 1 k2 Thus, by the Weierstrass Mtest, we have that X1 k=1 coskx k2 converges uniformly Since each partial sum is the sum of continuous functions, it is continuous Thus, since the convergence is uniform, the limit is also continuous on all R.
