math.hawaii.eduMath 241 Homework 12 Solutions Section 6.1 Problem 1. The solid lies between planes perpendicular to the x-axis at x=0 and x=4. The cross-sections perpendicular to the axis on the interval 0 ≤x≤4 are squares whose diagonals run from the parabola y=− √ xto the parabola y= √ x Solution From the picture we have s2 +s2 =(2 √ x)2 ⇔ 2s2 ...

sites.math.washington.eduMATH 402A - Solutions for Homework Assignment 3 Problem 7, page 55: We wish to find C(a) for each a ∈ S3. It is clear that C(i) = S3. For any group G and any a ∈ G, it is clear that every power of a commutes with a and therefore (a) ⊆ C(a) . Assume that a ∈ S3 and a 6= i. Then a has order 2 or 3. Thus, the subgroup (a) of S3 has order ...

These includes the upwards and downwards

Homework 1 Solutions - Montana State University
math.montana.eduHomework 1 Solutions 1.1.4 (a) Prove that A ⊆ B iff A∩B = A. Proof. First assume that A ⊆ B. If x ∈ A ∩ B, then x ∈ A and x ∈ B by definition, so in particular x ∈ A. This proves A ∩ B ⊆ A. Now if x ∈ A, then by assumption x ∈ B, too, so x ∈ A ∩ B. This proves A ⊆ A ∩ B. Together this implies A = A∩B.
