This week I am to find the equation of a line that is parallel or perpendicular to given lines that pass through specific point. The given equation y=12 x+3 The parallel line must pass through point (-2‚ 1) Parallel lines share the same slope so the slope of the new line will be12. Because I have an ordered pair and the slope‚ I can use point-slope to find the new equation Y-y1=m(x-x1)

Parallel arrays and arrays of structures An array of structures are usually equivalent to parallel arrays of the components. For example‚ if each student record consists of an ID number and a GPA value‚ then a list of students can be represented as an array of structure: The same data can be stored as two arrays that "parallel" to each other‚ in the sense that the same index in them indicate data for the same student: Usually the first way is more natural and convenient.

Fuzzy logic Definition: fuzzy logic‚ a multivalve (as opposed to binary) logic developed to deal with imprecise or vague data. Classical logic holds that everything can be expressed in binary terms: 0 or 1‚ black or white‚ yes or no; in terms of Boolean algebra‚ everything is in one set or another but not in both. Fuzzy logic allows for partial membership in a set‚ values between 0 and 1‚ shades of gray‚ and maybe-it introduces the concept of the "fuzzy set." When the approximate reasoning of fuzzy

INTRODUCTION Logic is the theory of the way in which people reason‚ with the aim of studying the principles of valid reasoning. The study of logic is the effort to determine the conditions under which one is justified in passing from given statements‚ called premises‚ to a conclusion that is claimed to follow from them. Logical validity is a relationship between the premises and the conclusion such that if the premises are true then the conclusion is true. There are several types of logic. The earliest
