Multiplying rational expressions is basically two simplifying problems put together. This video clip explains how to multiply rationals by factoring both numerators and denominators and identifying equivalents of one to cancel. Dividing rational expressions is the same as multiplying with one additional step—we take the reciprocal of the second fraction and change the division to multiplication. (1:41)
photos of children around the world
This video shows glimpses of children around the world, with a song by Tim Janis, in support of CROP Hunger Walks. The song is sung by school children in Kenya.
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)
Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.

Lose Yourself in the Digits - Song
This music video is to the tune of Eminem's "Lose Yourself" and teaches about the concept of Pi. Lyrics are not included on the screen but can be found at www.teachpi.org. The lyrics in the chorus are, "You better lose yourself in the digits of pi. It's a high but you got a thousand more to go. The numbers do not stop or drop into pattern, no. To memorize it would take most of a lifetime." (04:26)

9.520 Statistical Learning Theory and Applications (MIT)
Focuses on the problem of supervised learning from the perspective of modern statistical learning theory starting with the theory of multivariate function approximation from sparse data. Develops basic tools such as Regularization including Support Vector Machines for regression and classification. Derives generalization bounds using both stability and VC theory. Discusses topics such as boosting and feature selection. Examines applications in several areas: computer vision, computer graphics, t

Herramientas digitales en el proceso de dise?o en el taller de arquitectura [Digital Tools in the De
In the knowledge of previous discussions and academic experiences with the uses of digital tools in design process, some data has been collected among teachers and students to determine: .The nowadays role of digital graphic procedures in design for architectural works.. The study has been performed through exploratory research using: interviews, questionnaires and data analysis. The results shows the advantages and disadvantages of this type of design as well as allowed to come to conclusions a
Integrating Energy Design Into Caad Tools: Theoretical Limits and Potentials
The study is part of a research aims to establish theoretical grounds essential for the development of user efficient design tools for energy-conscious architectural design, based on theories in human factors of intelligent interfaces, problem solving, and architectural design. It starts by reviewing the shortcomings of the current energy design tools, from both architectural design and human factor points of view. It discusses the issues of energy integration with design from three different po
12.620J Classical Mechanics: A Computational Approach (MIT)
We will study the fundamental principles of classical mechanics, with a modern emphasis on the qualitative structure of phase space. We will use computational ideas to formulate the principles of mechanics precisely. Expression in a computational framework encourages clear thinking and active exploration. We will consider the following topics: the Lagrangian formulation; action, variational principles, and equations of motion; Hamilton's principle; conserved quantities; rigid bodies and tops; Ha
Exploraci?n de relaciones entre analog?as y bocetos durante la generaci?n de ideas en dise?o industr
An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and desi
Re-Evaluation and Recommendations for Redesign of the World Trade Center : Final Report
After the collapse of the World Trade Center, Towers 1 and 2, several questions were raised about the fire protection, egress and emergency evacuation systems. Full engineering services were provided to analyze the design of these systems to investigate what improvements can be made to keep the buildings standing longer, which could have saved more lives. Towers 1 and 2 each has a building footprint of an acre, stood 110 stories tall, housed 50,000 employees and an additional 26,000 visitors da
