... which we can think of as the “diagonal” viewed as a subset of X 2 . (Does the diagonal satisfy the test of being the graph of a function?) The preimage of A ⊆ X is just A. 2. A related example is inclusion: if X ⊆ Y , then {(x, x) : x ∈ X} is a subset of X × Y which is the graph of the inclusion fun ...

... In this project we explore three of the many applications of calculus to baseball. The physical interactions of the game, especially the collision of ball and bat, are quite complex and their models are discussed in detail in a book by Robert Adair, The Physics of Baseball, 3d ed. (New York, 2002). ...

... subsumes the previous two, as well as method 5, which follows. Any counting function likely to arise in practice can be computed from an algorithm, so the acceptability of this method will depend on the elegance and performance of the algorithm. In general, we would like the time that it takes the a ...

... Proof. Assume E 1 and E 2 are distinct normal forms for E : E ↔ E 1 and E ↔ E 2 . So E 1 ↔ E 2 and by the Church-Rosser Theorem I, there must exist an F such that E 1 → F and E 2 → F . However, since E 1 and E 2 are in normal form, E 1 = F = E 2 , a contradiction. ...

... Recall that a function is a rule that maps values from one set to another. In this course, we are mainly concerned with functions f : D → R, where D ⊆ R. Given the formula for a function f, we frequently have to figure out: • What is the domain of f? (The domain of f is the set of all ...

... Every point on a vertical line has the same xcoordinate, so a vertical line cannot represent a function. If a vertical line passes through more than one point on the graph of a relation, the relation must have more than one point with the same x-coordinate. Therefore the relation is not a function. ...

... Example: f (x) = x2 + 1 is continuous at all a. Defn (just terminology): f is continuous on an interval (open, closed, finite, infinite, etc.) if it is continuous at all points of the interval. Remember that continuity at an endpoint of the domain of f means that it is right- or left-continuous. Gra ...
