Geometry deals with shapes and the properties of those shapes. This documents discusses basic concepts of geometry. This e-book will be useful to students taking Geometry in high school and will become handy to those taking the SAT , GRE, GMAT Math section. The topics that are discussed in this e-book are as follows: 1. Polygons 2. Angles 3. Angles Properties in Circles 4. Circles, Chords, Tangents and Quadrilaterals

SAT Mathematics is a required entrance exam to many colleges and universities. Despite its importance, many students continue to struggle in it yet this exam is based on very common basic Math principles. When these ideas are reviewed in depth, any student is bound to boost their SAT score tremendously. This study guide is based on ideas that I have used to help students study SAT Math. I have had immense success in helping students succeed. One of my students recently scored a 770/800 in the

After teaching Math for many years, I have realized that many students lack the holistic approach to the concept of ratios, rates & fractions. Using these ideas in Math computations continues to be a challenge to many students in grade school, middle and high schools and even in colleges. With this e-book, it is my hope that I can help fill any gaps. Although this E-book is intended for grades 5-8; anyone who needs to understand the concept of ratios, rates and fractions and how we use them in

What is a metric system? The metric system is the measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. The easier way to memorize the metric system is by using the memorization line: “King Henry Died by drinking chocolate milk” Where: King has K standing for Kilo Henry has He standing for Hecto Died has D standing for Deca By had b standing for the basic unit in this case meter, liter or gram drinking has d standing for deci chocolate has c

In this New SAT Review, we present with examples the following: A. Quadratic functions and parabolas: Questions with answers B. Quadratic functions and Equations: Questions with answers C. Arithmetic and geometric sequence: Questions with answers D. Solving Ratios and proportions equations: Questions with answers

In our quest to help all students succeed in AP calculus, we hereby create a series of formulas that all AP students must master. These formulas are common differentiation and integration formulas as taught in a first level of calculus course in college. Differentiation is the process of finding a derivative of a function. On the other hand, integration is the process of finding the antiderivative of a function. In this e-document, you will find all the integration rules for power functions, e

The topic of special triangles is a very common topic that is tested in the SAT Math. However, many students fail in questions relating to this idea because of a lack of thorough practice on the subject. In this e-book, the topic of special triangles is discussed in great length common tricks, sample questions and answers. The student should find this review exciting and quite applicable in answering any SAT Math type question relating to special triangles.

The surface area of a solid object is a measure of the total area that the surface of an object occupies. This e-book details how to find the surface area of rectangular, triangular and cylindrical prisms. In geometry, a rectangular prism has 2 ends and 4 sides. Opposite sides have the same area. The surface area is the sum of the areas of all six sides. On the other hand, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joi

SAT Mathematics is a required entrance exam to many colleges and universities throughout the USA. Despite its importance, many students continue to struggle in it yet this exam is based on very common basic Math principles. When these ideas are reviewed in depth, any student is bound to boost their SAT Math score tremendously. This study guide is based on ideas that I have used to help students study SAT Math.

At the end of this lesson, 1. The student should be able to recognize that a given expression is the difference between two squares 2. The student should be able to apply the difference of two squares rule to factorize the expression

In this video, we present the distance, rate (speed), and time problems. By definition, Distance = time × rate or Time = Distance / rate or Rate = Distance / timeis used to solve uniform motion problems. Detailed solutions to the problems and explanations are provided.

The students will solve real-world and mathematical problems involving volume of cylinders, cones, and spheres. At the end of this lesson, the students should know the formulas for the volumes of cones, cylinders, and spheres and how to use them to solve volume related problems.

This lesson is essential in solving Math problems in grades 9 - 12. The students will learn how to break down numbers by identifying their products. The products of these numbers must include the highest perfect square of the number. The steps involved are as follows: Step 1: Find the largest perfect square that divides the number in the radical. Step 2: Break the radical expression such that the radical of a quotient is the product of the radicals. Step 3: Simplify the product by calculatin

Arithmetic Sequence is a sequence such as: 1, 3, 5, 7, 9, 11, 13, 15, 17 which has a constant difference between terms. The first term is a1, the common difference is d, and the number of terms is n. If a sequence of values follows a pattern of adding or subtracting a fixed number from one term to the next, then the sequence is referred to as an arithmetic sequence. The constant that is added or subtracted each time to get the next term is called the common difference, d.
