Inference and Proofs - Dartmouth Math Home
... We concluded our last section with a proof that the sum of two even numbers is even. That proof contained several crucial ingredients. First, we introduced symbols for members of the universe of integers. In other words, rather than saying “suppose we have two integers,” we introduced symbols for th ...

Number Line - Calculations in Science
... Turning a decimal into a fraction - put the decimal as a fraction with a denominator of '1' and then multiply top and bottom by whatever factor of 10 (eg 100, 1000, etc) will clear the decimal point to the extreme right. ...

On Angles Whose Squared Trigonometric Functions are Rational
... There are many additive relations between angles of this kind; for instance α and β satisfy α + 2β = 2π. In this paper we essentially classify all such additive relations. To be precise, we shall say that θ is a “pure geodetic angle” if any one (and therefore each) of its six squared trigonometric f ...
