... Proposed Research Topic: The Role of Linear Algebra in Projecting the Success of a Web Based Business Purposes: For many people, students and non-students alike, the essence of Linear Algebra is not much appreciated with the knowledge that this subject is only for those who are specializing in mathematical studies. On the contrary, mathematics is an everyday experience for us though usually not greatly observable. It is the goal of this research to let linear algebra be employed in the famous world of business, where else but the use of internet. This would be an interesting field to apply the study of linear algebra as it gives a twist to the misconstrued perception that linear algebra is just...

Students’ Persistent Algebra Difficulties
The National Curriculum has for many years set forth standards for teaching algebra to students from ages younger than 16 years through 19 years. An extensive analysis of the impact of these standards was conducted by the Joint Mathematical Council and The Royal Society during 1994-1997. It concluded that the standards were not achieving adequate results from students, and made many recommendations for improve...

... Affiliation Algebra Questions chosen are question 2, 4 and 5 Question 2 The degree of the function x2(x-2)3 canbe determined by first expanding the function and then the terms are put in decreasing order of their exponential. . The function is then expanded as shown below.
The expansion of (x-2)3 is first done and the result multiplied by x2
x2(x-2)3
x2(x3- 6x2 + 12x - 8)
x5- 6x4 + 12x3 - 8 x2
The coefficients of the function are not necessary for the determination of the degree of the polynomials, therefore they are ignored and the equation rewritten as:
x5- x4 + x3 - x2
The power of the largest term is then identified. For this function, the largest term is the first term with the power of 5.

1) A description of rotations through an angle about the origin.
Each of the conic sections which are centered at the origin can be described by the equation
Ax2 + Cy2 + Dx + Ey + F = 0
This curve can be rotated through an angle about the origin by using the rotation equations:
x = x’ cos - y’ sin
y = x’ sin + y’ cos
so that the transformation matrix is:
R =

For the cofactors we will put the minor and a (“+1” or a “-1”) which depends on sign required for each minor. This signs will be by going to our “sign matrix” above beginning at the 1st entry in the particular row or column we are expanding along (Larson, & Falvo 110). After that as we move on that column or row we will put the sign required in that case.

... 20 June Algebra Question 12 In a graph of y against x where x includes the variables that form an equation of y to x, an increase or decrease in x values result into a considerable change in the upward or downward opening of the graph. The graph opens up when x gets more and more positive (Knapp, 20). That is, a positive increase in x values results into positive increase in the y value thus makes the graph to move upwards (open up). On the other hand, when x values get more and more negative the graph opens down. That is, as the values of the variable x get more and more negative, it consequently results in the reduction of the y value. Thus this leads to the graph to move downwards open down...

The value of pi, 3.14, is a mathematical constant in which the circle is defined. The value of pi is found through calculation of the circumference divided by the diameter. The size of the object does not vary because the ratio between the circumference and the diameter is always constant to 3.14. When manufactures make a glass, a coffee mug, etc., the ratio is kept the same due to the constructs of the circle. This is because it remains constant.

... Lesson Plans by JT Thomas 6-21-2006 Lesson Multiplicative Inverses Introduction The purpose of this lesson is to introduce tothe concept of multiplicative inverses. By using the fact that 0 doesnt have a multiplicative inverse, it is shown that division by 0 is not defined.
2.Introductory Examples
To find a multiplicative inverse of a number x, we must find the number that when multiplied by x, equals 1:
x * (multiplicative inverse) = 1
This number is always the reciprocal 1/x, since after canceling x in the numerator and denominator we are left with 1 multiplied by 1:
x * (1/x) = 1 * 1 = 1
For instance, to find the multiplicative inverse of 6, we just divide 1 by 6:
6 * (1/6) = 1

The constant is approximately 2.71828182845…; however, the number has been estimated to a fairy high degree of accuracy. Being a rational number implies that e has indeterminate decimals. The Euler’s numbers servers as the base to the natural logarithm.
The Euler’s constant can be derived through several methods and each of these methods depends on the intended use. The first method is based on the infinite series theory. From this method e is the limit of (1 + 1/n) {n± 0} or (1 + 1/n!) as n tends to infinity. Therefore e = 1 + 1/1 + ½ + 1/3 + ¼ …. Alternatively, e =1 + 1 + 1/ (1× 2) + 1/ (1 × 2 × 3...

... fractions are fractions that can include a numerator, denominator and an extra number. In this case, the simplification of a mixed fraction is done by converting it into an improper fraction and then converting into integers. To simplify 16 1/2, multiply 16 and 2 and the result will be 32, which is summed up with 1 which gives 33/2. This improper fraction can be further simplified by finding the quotient of the equation, which is a number with a decimal point, 16.5 (Szecsei, 2006)
