Why didn't you guys are answering my questions at all. 8 question posted tomorrow but not even a single question is answered yet.

Answer 1

Watson I have not been on in weeks but let me edit your question...

Why aren't you guys answering my questions? I posted 8 questions yesterday, and not a single one has been answered yet.

Now on to why questions don't get answered, most of the time it is because people post their questions and do not provide us with their attempt(s) at answering them. We do not answer most questions outright, we are here to help you find the answers yourself. To do that we need you to show us what you know, so we have some idea of how to assist you in learning the subjects. We want you to learn, that is our goal.

Answer 3

And this problem:

http://www.jiskha.com/display.cgi?id=1366763364

is trivial, obviously the problem is wrong because alpha*beta can't possibly be zero, but it's quite easy to figure out that it should be minus one, the identity then follows almost immediately.

It's not clear to me why Watson would repost that same problem with that obvious typo, because if it isn't immediately obvious you would not have the skills to tackle these sorts of problems.
