In a computer science class, there are 14 students who have previously written a program in Java, and 12 students who have previously written a program in Python. How many students have previously written a program in at least one of the two languages? (If you can’t give a single number as a definitive answer, give as narrow a range of possible values as you […]

Recall the relation successor :=  hx, x + 1i : x _ Z_0 . Prove by induction on k that, for any integer x and any positive integer k, we have that hx, x + ki is in the transitive closure of successor. (In other words, you’re showing that the transitive closure of successor is _. Note that you cannot rely on the algorithm in […]

(programming required) The reason that sn is called the “Fibonacci word fractal” is that it’s possible to visualize these “words” (strings) as a geometric fractal by interpreting 0s and 1s as “turn” and “go straight,” respectively. Specifically, here’s the algorithm: start pointing east. For the ith symbol in sn, for i = 1, 2, . . . , |sn|: if the symbol is 1 then […]

The hydraulic cylinder is subjected to three forces. An 8-kN force is exerted on the cylinder at B that is parallel to the cylinder and points from B toward C. The link AC exerts a force at C that is parallel to the line from A to C. The link CD exerts a force at C that is parallel to the line from C to […]

Consider the set A := {1, 2, . . . , n}. Consider the following claim: there exists a relation  on the set A that is both an equivalence relation and a partial order. Either prove that the claim is true (and describe, as precisely as possible, the structure of any such relation ) or disprove the claim.
