Brainstorming About the College Application Essay Brainstorming The most important part of your essay is the subject matter. To begin brainstorming a subject idea, consider the following points. From this brainstorming session, you may find a subject you had not considered at first. Finally, remember that the goal of brainstorming is the development of ideas -- so don't rule anything out at this stage. See if any of these questions help you with developing several ideas for your college essay. * What are your major accomplishments, and why do you consider them accomplishments? Do not limit yourself to accomplishments you have been formally recognized for since the most interesting essays often are based on accomplishments that may have been trite at the time but become crucial when placed in the context of your life. * Does any attribute, quality, or skill distinguish you from everyone else? How did you develop this attribute? * Consider your favorite books, movies, works of art, etc. Have these influenced your life in a meaningful way? Why are they your favorites?
• What was the most difficult time in your LIFE AND HOW DIDI YOU OVERCOME?

Make Tables, describe in words, draw a picture, write and solve equations What ever you do, do it better than any one else. Just Make it your own. Example: The height of a tree was 7 inches in the year 2000. Each year the same tree grew an additional 10 inches. Write an equation to show the height h of the tree in y years. Let y be the number of years after the year 2000. The most literal equation might be 7 + 10y = h.

Multiplication of Polynomials Multiplication of a Polynomial by a Monomial To multiply a polynomial by a monomial, use the distributive property: multiply each term of the polynomial by the monomial. This involves multiplying coefficients and adding exponents of the appropriate variables.

Table of Formulas For Geometry A table of formulas for geometry, related to area and perimeter of triangles, rectangles, cercles, sectors, and volume of sphere, cone, cylinder are presented. Right Triangle and Pythagora's theorem Pythagora's theorem: The two sides a and b of a right triangle and the hypotenuse c are related by a 2 + b 2 = c 2 Right Triangle Area and Perimeter of Triangle Triangle Perimeter = a + b + c There are several formulas for the area. If the base b and the corresponding height h are known, we use the formula Area = (1 / 2) * b * h.
88
If two sides and the angle between them are known, we use one of the formulas, depending on which side and which angle are known Area = (1 / 2)* b * c sin A Area = (1 / 2)* a * c sin B Area = (1 / 2)* a * b sin C . If all three sides are known, we may use Heron's formula for the area. Area = sqrt [ s(s -‐ a)(s -‐ b)(s -‐ c) ] , where s = (a + b + c)/2. Area and Perimeter of Rectangle Rectangle Perimeter = 2L + 2W Area = L * W Area of Parallelogram Area = b * h Area of Trapezoid Trapezoid Area = (1 / 2)(a + b) * h Circumference of a Circle and Area of a Circular Region CircleCircumference = 2*Pi*r Area = Pi*r 2 Arclength and Area of a Circular Sector Sector Arclength: s = r*t Area = (1/2) *r 2 * t where t is the central angle in RADIANS. Volume and Surface Area of a Rectangular Solid Sector Volume = L*W*H Surface Area = 2(L*W + H*W + H*L) Volume and Surface Area of a Sphere Sphere Volume = (4/3)* Pi * r 3 Surface Area = 4 * Pi * r 2 Volume and Surface Area of a Right Circular Cylinder Volume = Pi * r 2 * h Surface Area = 2 * Pi * r * h Volume and Surface Area of a Right Circular Cone right cone

Simple Polynomial Multiplication (page 1 of 3) Sections: Simple multiplication, "FOIL" (and a warning), General multiplication
105
There were two formats for adding and subtracting polynomials: "horizontal" and "vertical". You can use those same two formats for multiplying polynomials. The very simplest case for polynomial multiplication is the product of two one-‐term polynomials. For instance: * Simplify (5x2)(–2x3) I've already done this type of multiplication when I was first learning about exponents, negative numbers, and variables. I'll just apply the rules I already know: (5x2)(–2x3) = –10x5 The next step up in complexity is a one-‐term polynomial times a multi-‐term polynomial. For example: * Simplify –3x(4x2 – x + 10) To do this, I have to distribute the –3x through the parentheses: –3x(4x2 – x + 10) = –3x(4x2) – 3x(–x) – 3x(10)
106
= –12x3 + 3x2 – 30x The next step up is a two-‐term polynomial times a two-‐term polynomial. This is the simplest of the "multi-‐term times multi-‐term" cases. There are actually three ways to do this. Since this is one of the most common polynomial multiplications that you will be doing, I'll spend a fair amount of time on this. * Simplify (x + 3)(x + 2) The first way I can do this is "horizontally"; in this case, however, I'll have to distribute twice, taking each of the terms in the first parentheses "through" each of the terms in the second parentheses: Copyright © Elizabeth Stapel 2006-‐2008 All Rights Reserved (x + 3)(x + 2) = (x + 3)(x) + (x + 3)(2) = x(x) + 3(x) + x(2) + 3(2)
107
= x2 + 3x + 2x + 6 = x2 + 5x + 6 This is probably the most difficult and error-‐prone way to do this multiplication. The "vertical" method is much simpler. First, think back to when you were first learning about multiplication. When you did small numbers, it was simplest to work horizontally, as I did in the first two polynomial examples above: 3 Å~ 4 = 12 But when you got to larger numbers, you stacked the numbers vertically and, working from right to left, took one digit at a time from the lower number and multiplied it, right to left, across the top number. For each digit in the lower number, you formed a row underneath, stepping the rows off to the left as you worked from digit to digit in the lower number. Then you added down. For instance, you would probably not want
108
to try to multiply 121 by 32 horizontally, but it's easy when you do it vertically: 121 Å~ 32 = 3872 You can multiply polynomials in this same manner, so here's the same exercise as above, but done "vertically" this time: * Simplify (x + 3)(x + 2) I need to be sure to do my work very neatly. I'll set up the multiplication: multiplication ...and then I'll multiply: multiplicationIf you want to use FOIL, that's fine, but (warning!) keep its restriction in mind: you can ONLY use it for the special case of multiplying two binomials. You can NOT use it at ANY other time! * Simplify (x – 4)(x – 3) multiplication So the answer is: x2 – 7x + 12 Using FOIL would give:
109
"first": (x)(x) = x2 "outer": (x)(–3) = –3x "inner": (–4)(x) = –4x "last": (–4)(–3) = +12 product: (x2) + (–3x) + (–4x) + (+12) = x2 – 7x + 12 * Simplify (x – 3y)(x + y) multiplication So the answer is: x2 – 2xy – 3y2 Using FOIL would give: "first": (x)(x) = x2 "outer": (x)(y) = xy "inner": (–3y)(x) = –3xy "last": (–3y)(y) = –3y2 product: (x2) + (xy) + (–3xy) + (–3y2) = x2 – 2xy – 3y2 Let me reiterate what I said at the beginning: "FOIL" works ONLY for the specific and special case of a two-‐term expression times another two-‐term expression. It does NOT apply in ANY other caseA figure can represent
