The mathematics that leads to the proof of the nontrisectibility of an arbitrary angle is beautiful, it is accessible, and it i

Divisibility in the Integers,? and is very familiar to us-in fact, we were introduced to this set so early in our lives that we think of ourselves as having grown up with the integers! Moreover, we view ourselves as having completely absorbed the process of integer division; we unhesitatingly describe 3 as dividing 99 and equally unhesitatingly describe 5 as . dividing 101.

The Field Generated by an Element,ether there is some property of . that would determine whether .[.] = .(.), and we were wondering what the relation is between the element . and the degree of .(.) over .. We had alluded to the minimal polynomial of . over ., but we had to delay discussing this concept until we had first studied polynomials.

Rings and Fields,In the previous chapter we studied the integers in detail, focusing on divisibility properties. Divisibility, of course, is defined via multiplication: we say . divides . if . for some integer .. What we did not do in the last chapter is go deeper still-we did not analyze multiplication itself.
