Binary Tree Induction

# Recall that a binary tree can be defined recursively as: * A Binary Tree is either empty * or A Binary Tree consists of a node with a left and right child both of which are Binary Trees. The degree of a node in a tree is equal to 0 if both children are empty, 1 if one of the children are empty, and 2 of both children ar

Grammar Induction

Consider the grammar 1) <Number> -> <Digit><Number>|epsilon 2) <Digit> -> 0|1|2|3|4|5|6|7|8|9 Use induction to show that the number of strings in L(<Number>) of length n is equal to 10^n

Clearly identify the variables, coefficients, and constants

Translate the following into algebraic expressions. Clearly identify the variables, coefficients, and constants: a) One fourth of one half of the product of two numbers b) Two-thirds of the quotient of two numbers c) The product of 7 and twice n


Lydia takes ten minutes more to complete an illustration than Tom. The total time taken by both of them is six hours. Form an algebraic equation to express this and identify the variables, coefficients, and constants of the algebraic expression. You are not required to solve the equation.

Measurement of Angles

1. In a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [The sum of the measures of three interior angles of a triangle is always 180 degrees.] Form an algebraic equation to express the problem and identify the variables, coefficients,

Finite Set of Embeddings

Let E be a finite extension of a field F. Show that any finite set of distinct embeddings of E into the algebraic closure of F is linearly independent over F.

Let G, H be graphs such that G is a subgraph of H. Prove or disprove each of the following: (a) alpha(G) <= alpha(H) (b) alpha(G) >= alpha(H) (c) omega(G) <= omega(H) (d) omega(G) >= omega(H)

The stability number, alpha(G), of a graph G is the cardinality of the largest subset S of V(G), the vertex set of G, such that no two of the vertices in S are connected by an edge of G. The clique number, omega(G), of a graph G is the cardinality of the largest subset S of V(G), the vertex set of G, such that every pair of

Syntactic categories

Write productions that will define the syntactic category <SimpleStat>, to replace the abstract terminal simpleStat in the figure below {see attachment}. You may assume the syntactic category <Expression> stands for C arithmetic expressions. Recall that a "simple statement" can be an assignment, function call, or jump, and that

Proof about congruence modulo 43 (also expressible as equivalence modulo 43)

Let S = Z_43 (where the underscore, "_", indicates that what follows it, in this case 43, is a subscript). Let Q be a subset of S that contains ten non-zero numbers (i.e., that Q contains ten non-zero elements of S). Prove that Q contains four distinct numbers "a," "b," "c," "d" such that ab = cd in Z_43.
