Let A1,A2,...,An be attribute names with associated domains D1, D2, . . . , Dn, then R(A1: D1,A2: D2,...,An: Dn) is a relation schema. For example, Student(StudId: integer, StudName: string, Major: string) • A relation schema specifies the name and the structure of the relation. • A collection of relation schemas is called a relational database schema. * 1. List the names of all students who have borrowed a book and who are CS majors. πStName(σSTUDENTS.StId=borrows.StId (σMajor=’CS’(STUDENTS)×borrows))

point in vacuum world, then pure reflex agent can not be rational. c. True. If every action results in the same result, no matter what the agents do, they get the same reward. Then every agent is rational. d. False. The input of the agent function is percept history, yet the input of the agent program is only the current percept which is the only thing it can get from the environment. e. False. When the agent needs to keep putting every percept into the percept sequence and can not delete

10.2. Need for hidden line and surface elimination algorithms When we attempt to view a picture that contains some non-transparent things or surfaces, then those objects or surfaces are hidden from us i.e. we cannot view those parts that are behind the objects that we can see. We should remove such hidden surfaces to get a realistic view of an image. Hidden surface problem is a process in which we identify and remove the hidden surfaces of a picture as shown in figure 10.1. Objects in computer

Honors Algebra II Supplemental Notes Oblique Asymptotes Key Concepts: An oblique asymptote is an oblique, or slanted, line that the graph of a function approaches, but never touches, as x → ∞ ( x approaches infinity). To find the oblique asymptote of a rational function: 1. Reduce the rational function P( x) to lowest terms. An oblique asymptote can be found Q( x) when the degree of P ( x) is one greater than the degree of Q ( x ) . c 2. Divide P ( x) by Q ( x ) using long division to get

Polynomial functions mc-TY-polynomial-2009-1 Many common functions are polynomial functions. In this unit we describe polynomial functions and look at some of their properties. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: • recognise when a rule describes a polynomial function, and write down the degree
