17. Fix a nonzero complex number Zo. Show that the set D obtained from the plane by deleting the ray {tz: 0<t< 0} is a domain.
Please answer B4 B4. Show that f(z) -sin(1/z) achieves any complex value infinitely many times in every neighborhood of its essential singularity z 0 B5. Prove that for a fixed w in the unit disk D, that is, lw 1, the fractional linear transformation F(z) = u 12 satisfies the following conditions: (a) F maps the unit disk D to itself and is holomorphic. (b) |F(z)-1 if |zl-1, and |F(z)> 1 if |2l > 1.

part iii and iv Exercise 3 (Paired test, known variance of the difference). Let X, Y be RVs. Denote E[X] = Hx and E[Y] = My. Suppose we want to test the null hypothesis Houx = uy against the alternative hy- pothesis H :Mx My. Suppose we have i.i.d. pairs (X1,Y),...,(Xn, Yn) from the joint distribution of (X,Y). Further assume that we know the value of o2 = Var(X-Y). (i) Noting that X1 - Y1,...,xn - Yn are i.i.d. with...
Number Theory 13 and 14 please! 13)) Let n E N, and let ā, x, y E Zn. Prove that if ā + x = ā + y, then x-y. 14. In this exercise, you will prove that the additive inverse of any element of Z, is unique. (In fact, this is true not only in Z, but in any ring, as we prove in the Appendix on the Student Companion Website.) Let n E N, and let aE Z...
