Proportions in mathematics can be viewed from a few perspectives. For instance‚ the proportionality of two variable values is determined by checking if one of the values is the product of the other value and some constant. In other words‚ two variable values (numbers or quantities) are proportional if their ratio is a constant‚ called the coefficient of proportionality or the proportionality constant. This is best explained using the linear equation: y = k*x If k is a constant quantity‚ x will

Arithmetic and Logical Operations Chapter Nine There is a lot more to assembly language than knowing the operations of a handful of machine instructions. You’ve got to know how to use them and what they can do. Many instructions are useful for operations that have little to do with their mathematical or obvious functions. This chapter discusses how to convert expressions from a high level language into assembly language. It also discusses advanced arithmetic and logical operations including

Introduction How do the ancient Egyptians build the pyramids? It is not easy to answer these questions‚ especially if there is not that much information left. The Egyptians were one of the first civilizations to develop a written language‚ evidence of this amazing literary work is still engraved stone walls‚ obelisk and tombs in every ancient city of Egypt. However; no literature of any kind in those places that describe the mathematics used to construct all those extraordinary monuments. The

ence of two squares DIFFERENCE OF TWO SQUARESThis formula is used to factorise some algebraic expressions. Example 5Solution: | FACTORING THE SUM AND DIFFERENCE OF TWO CUBES The formula for factoring a sum of two cubes is: | x3+y3=(x+y)(x2−xy+y2) | | The formula for factoring a difference of two cubes is: | x3−y3=(x−y)(x2+xy+y2) | | When teaching these factorization methods‚ it may be a good idea to encourage students to know one method for these factorizations rather than have them

These are usually presented as‚ "How does A affect B?"‚ where A is your independent variable and B is your dependent variable. Describe the independent and dependent variables in terms of whether they are nominal (also called categorical)‚ ordinal‚ interval‚ or ratio variables (interval or ratio variables are also called continuous variables).

Example : 7‚ 3‚ -2‚ 3/7‚ etc. are all constants. Variables : A symbol which may be assigned different numerical values is known as variable. Example : C - circumference of circle r - radius of circle Where 2 & are constants. while C and r are variable Algebraic expressions : A combination of constants and variables
