The Wikipedia

http://en.wikipedia.org/wiki/Engineering

http://en.wikipedia.org/wiki/Portal:Engineering

Engineering is huge. To give a brief overview of areas that engineering covers can take up an entire Fast Track in itself thankfully, we don’t need to do that. The Wikipedia entries are more than comprehensive. the Engineering article, which is an overview of the entire discipline, as well as the engineering portal, which is a more in-depth look at the field and its many branches. What started out as independent branches of study are increasingly becoming strong in inter-disciplinary skill requirements. The portal will be useful in helping you keep up-to-date with the entire field while keeping you in touch with your branch of study as well.

Massachusetts Institute of Technology

http://ocw.mit.edu

The Open Courseware (OCW) education program is a free and open online educational resource made Available by many universities around the world. One of the major contributors to this program is the world renowned Massachusetts Institute of Technology (MIT). Through the OCW program, you get access to the teaching syllabus, lecture notes, and textbooks used in many of the courses taught at MIT.

Engineering Formulas

www.efunda.com

This is an online referencesite for engineers and engineering students who want a quick way to access a forgotten formula. It also contains quick reference information regarding many engineering topics. It is a paid site—about Rs 300 per month or for students about Rs 1,800 per year. Currently you also get a review period when you first eFunda—Formulas in a snap access the site, so you can go through the actual contents before deciding on whether you want to become a member or not.

Mathametics,trigonometry website

1 Webmath.com

www.webmath.org

Help is available in various categories, including the usual suspects—trigonometry, calculus, algebra, and so on. There are two ways to use the site—one is by browsing the tabs, and the other is by “Quick Jumping” to a topic of your choice.


2 Algebra Review in Ten Lessons

http://math.uakron.edu/%7Edpstory/mpt_home.html

If you can’t follow what’s going on in class, or if you need assistance with a particular type of problem, browse through the chapters and you’re sure to find a lucid explanation. Story takes pains to explain each and every step of what’s going on, which cannot be said about many textbooks (or professors). Highly recommended if you want a serious understanding of basic, and
even not-so-basic algebra.


3 Dave’s Short Trig Course

www.clarku.edu/~djoyce/trig/

After calculus, trigonometry is one of the toughest areas of highschool maths to master. “These notes are more of an introduction and guide than a full course,” as it says on the site. Use it to supplement your existing textbook.


4 The Math Forum @ Drexel

www.mathforum.org/dr.math/

the Math Forum discovered a dormant project called “Ask Prof. Maths,” where K-12 students could send in math questions and get personal answers



5 Homepage of e-Calculus

www.math.uakron.edu/%7Edpstory/e-calculus.html

As in one other site maintained by Prof D P Story that we’ve mentioned here, this one, too, is nothing site-wise: it’s a collection of PDFs.You’ll want to download them: they teach the subject well! Here’s an extract from somewhere near the beginning of the course



6 Euclid’s Elements

http://aleph0.clarku.edu/%7Edjoyce/java/elements/toc.html

Euclid’s Elements is the most successful textbook ever written. It was one of the very first works to beprinted after the printing press was invented, and is second only to the Bible in number of editions published.


7 EqWorld

http://eqworld.ipmnet.ru/en/solutions/ode.htm

Equations, more equations, then some more equations thrown in for good measure—that’s what you’ll find at this site. Not for the faint of heart or head, and, indeed, probably useful only as a quick reference for solutions to various advanced (and some not-so-advanced) equations.

8 Algorithms And Complexity

www.cis.upenn.edu/%7Ewilf/AlgComp3.html

A book for you to download—no more fumbling over what’s NP-Hard This is not a site; it’s just the download page for Algorithms and Complexity, by Herbert S Wilf. The “algorithms” part of the book is pretty standard, but we’re recommending the “complexity” part of the book. Still puzzled over what NP-completeness is? Still wondering what “NP-hard” means? Download this book!



9 Wolfram MathWorld

http://mathworld.wolfram.com/

12,646 entries. The big daddy of all the maths sites there are on the Web,Wolfram MathWorld is your single stop for everything maths—with a caveat: you’ll sometimes need to wade through incomprehensible stuff to get to something simple enough for you to Ah, Eric Weisstein again!
understand!
