Discover the world's most endangered species Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Despite appeals for support, just 85 of our 5.6 million users in 2018 made a donation.

Our team of top teacher mathematicians have put together all the important topics and explain them with the types of examples that you would find in a normal textbook or exam. Page 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 a cos x + b sin x = R cos(x - a) a cos x + b sin x = R cos(x - a) . In this unit we explore how the sum of two trigonometric functions e.g. 3 cos x + 4 sin x, can be expressed as a single trigonometric function. Having the ability to do this enables us to solve trigonometric equations and find maximum and minimum values.
Educational Videos and Games for Kids about Science, Math, Social Studies and English Nota : Casual Collaboration (Tools) 2012 Kavli Contest Themes Join hundreds of the world’s leading scientists, engineers, thinkers, and innovators as we tackle mankind’s greatest challenges and help to build our future. Our contest theme this year was inspired by the National Academy of Engineering (NAE) Grand Challenges. "Meeting these challenges would be 'game changing,'" says NAE president Charles M. Vest. "Success with any one of them could dramatically improve life for everyone and may even be required for our survival." We are challenging you to: 1. THE NEXT GREAT SOLUTION. 2. THE NEXT GREAT FRONTIER. 3. THE NEXT COOL TOOL. The National Association of Secondary School Principals has placed this program on the NASSP National Advisory List of Student Contests and Activities for 2011-2012.
