NO question AT  ALL  is displaying for me.  I wonder why not.

can other people see a question here?

4338 can obviusly see a question.  ?????

Guest, I am wondering why you put this function equal to zero?   There is no =0 in the question.     :///

f(x) = − √ 2 − x^2

There is no question here at all !

Thanks Alan,

I did not think it was a simple answer.

I played around with it but I didn't really get anywhere :)

"On this website everyone seems to ignore me.  saying that i am rude is being rude and i gave it 16 minuets"

Look I really understand what you are saying.   Good help is so hard to come by these days.

It is always best to make demands on people, be really rude and demand that they tend your every need immediately.

Never say please or thank you and never pay them in money or gratitude.  

Never give anything in return, just winge very loudly when you do not get what you demanded immediately.

Yes I can see why you are so upset!  Of course people should kiss your feet in gratitude when you make demands upon them.

How rude all your  slaves, er servants, er, other forum members and guests are!!!

Something really should be done about it !!   

Thanks Alan,

YES, that is exactly how I did do it - I was looking at yours and at Wolfram|Alpha.

But it still started by dividing everything by dx.      :/

The forum is doing some really weird things.

Last night when I tried to remove threads from my watchlist, and once when I wanted to post a new solution.  The thread was downloaded to my computer instead.

And now, my wrap lantern from yesterday, which is still there if I paste the address straight into the address bar

http://web2.0calc.com/questions/wrap-lantern-sun-29-11-15

Is no where to be seen in the 'questions list' 

This happened to me once before when I was looking for one of Mellie's questions.

Also some of the posts are displaying and then going blank later on.  Anonymous4338 gave a detailed answer to a question, and then the question disappeared.  I mean it was still there but it was just white space.  Weird!!!

Also of coursethe picture insert is not working.  Or, at least, a lot of people have said it is not working. I must not have tried to insert anything since it has been broken.

STRANGER DANGER

Thanks very much Alan for these instructions.

This would be a good one to do a graphing solution too.  I'll do that if I ever get up to it ://

Hi Alan and others,

I have only just come back to this question to take a proper look.

Prior to watching you one the forum I never treated calculus dy and dx so much like normal algebra.

To me dy/dx was glued together with super glue.

I guess I understood better when I was studying at university but I do not remember that.

It all makes such perfect sense when you show me how to do things.  

Working through this with you and WolframAlpha as a guide made it so easy.

 BUT, if I come back in a fortninght and try to do it myself I won't be able to.

Isn't that sad. :)

Students often tell me that I do not understand their learning problems, but you see I really do!    

what is 3X + 6???

It is an algebraic expression.

It cannot be simplified and since there is no equal sign there is nothing to solve.  :)

Thanks for letting me know,

It works now :)
