you get benefited by my effort.your feedback is very much precious
to me.Thank you.
1. (a) Show that ez 3 2 = + if and only if 2 = ( +20k) : + 2nk i for k e Z. 2
Show that: Ez = ,(€r – Ey) 0x = Entretien Oy = E( using the General Hooke's Law equations, € =-v.- v. &z=-v. v. if Ex, Ey, and v are known values and 0, = 0
Let a EC Z such that a? EZ and Rea=0. Let N: Z[0] → Z:2H |212. (a) Show that N() NU {0} for all ze Z[a], and that if ry in Za], then N (2) N(y). (b) Show that Z[a] satisfies the ascending chain condition for principal ideals. (e) (Bonus) Show that Z[iV2 is a Euclidean domain. (Hint: there's a proof in the textbook that Z[i] is a Euclidean domain that you can modify.) (d) Show that Ziv5) is not...
