1. practice assignment 1: summation notation problem 1.1. consider the sequence of natural numbers an = 2n2 1, for n 2 n. compute the following expressions: (1) an4 . (2) an·aa3 . (3) aaai .
Summation in mathematics is the addition of a series of any type of numbers, known as addends or summands; the result is their sum or total.
Other sorts of values, in addition to integers, can be summed: functions, vectors, matrices, polynomials, and, in general, elements of any form of mathematical object on which an operation marked "+" is specified.
Series are summations of infinite sequences. They are related to the idea of limit and are not addressed in this article.
A succession of adds is used to represent the summation of an explicit sequence. For example, the sum of [1, 2, 4, 2] is denoted 1 + 2 + 4 + 2 and yields 9, i.e. 1 + 2 + 4 + 2 = 9. Because addition is associative and commutative, no parentheses are required, and the result is the same regardless of the order of the summands.
The sum of a sequence containing only one element yields the element itself. By convention, summation of an empty sequence (a sequence with no items) yields 0.
The components of a series are frequently described by a regular pattern as a function of their location in the sequence. For basic patterns, summation of lengthy sequences can be represented by ellipses in most summands.

Add an edge between two labeled vertices only if another edge of the same label doesn't exist?
Yes, you can add an edge between two labeled vertices only if another edge of the same label doesn't exist.
What is the vertices ?
A vertex, also known as a node, is a point in a graph that represents a relationship between two or more objects. A vertex may also be referred to as a corner, or a junction. In mathematics, a vertex is the point at which two or more curves, lines, or edges meet. In a graph, each vertex is associated with a set of edges, where an edge is a line or an arc that connects two vertices. Vertices can be used to represent data points, locations, and objects. For example, a vertex might represent the location of a city, the age of a person, or the cost of a product. Vertices can represent physical objects, such as buildings, and they can also represent abstract concepts, such as relationships or ideas.

why do we designate one of the candidate keys of a relation to be the primary key?
Designating one of the candidate keys as the primary key allows the database to enforce relationship constraints, maintain data integrity, and optimize performance.
Why decide one of the candidate keys?You designate one of the candidate keys of the relation as the primary key for several reasons.
Uniqueness:
A primary key must uniquely identify each tuple (row) in the relation. This ensures that each tuple has a unique identifier, making data easier to manage and avoiding duplicate entries.
Referential integrity:
Primary keys are used to establish referential integrity between tables. When a table references another table through a foreign key, the foreign key values must match the primary key values of the referenced table.
Data consistency:
Using primary keys ensures data consistency across databases. When data is inserted or updated, the specific tuple to be updated is identified using the primary key so that the correct data is changed.
performance:
A primary key is often used as an index on a relationship, which improves query performance. Retrieving data using the primary key allows the database to access the data faster than if it had to search the entire table.

It is considered as poor programming practice as it again to save years as two digits, as was done in the Y2K bug, as this could result in uncertainty and loss of data.
How programming practice takes place?It is seen as poor programming practice to save years as two digits, as was done in the Y2K bug, as this might result in ambiguity and data loss. Assuming that the decade 2000 would've been represented as "00" led to the Y2K problem, which could have led software to mistakenly read the year as 1900 rather than 2000.
It is advised to adopt a format that can accept diverse types of dates and times, such as the ISO 8601 standard, or to save years using four digits in order to prevent these types of problems.
