I think rein-outs right this place wouldnt be the same if you implied those rules.The main reason i come here now(because of summerbreak) is to joke around.But if the rules were added this place wouldnt be the same.....

Ah....I see what you mean, reinout!!!  Sorry, I misread it !!!

Hey Chris, 

I think the person that asked this question actually wanted an explanation why this works .

Now it does somehow seem logical in my head, but I'm too tired to be able to put it on paper.

Will you have another look at it?

Otherwise I'll have a look at it tomorrow or the day after tomorrow... 

How fast do you want us to be?

Did it take that long for you to get an answer?

What question did you ask?

Reinout

Let's start with the fact that the terms sin^-1 asin and arcsin are all terms for the inverse sin (so they all mean the same)

Then if

sin(b) = c

b = asin(c) [I use asin here because on the calculator of this forum it's also asin]

Does this help?

I thought this might be the best place to say this but I don't think it's a good idea to ask Andrew to have threads which stick to the top of the forum. I think these threads will strongly discourage new members to post a question on this forum. As long as we don't have these threads, the forum still has a 'from people for people' feel. It doesn't matter what kind of question you ask since the people on the other side also feel like people. If you add these kind of 'rules for posting' threads it will feel like the person asking the question is asking it to mathematicians with little time that don't want to be bothered with 'stupid' questions. In short, I think it will strongly discourage the playfulness of the forum, which is basically the main strength of the forum. 

That's my opinion about this, but maybe someone else could give his opinion about this too.

Reinout

Maybe we can or maybe we won't.        

Maybe. How much extra are you willing to pay?

......................................................

Let's try this....maybe the bottle of pills costs $80........???

So, 80/30 = 8/3  = 2 + 2/3    =  about  $2.66 per pill

To borrow a term from ND ....that is "spendy!!!"  (my new Word of the Day!!!)

BTW....I agree with rosala.....definitely a "museum" piece  !!!

We would have to know the area and the size of a tile !!!

I actually don't know how to get the inverse, mathematically......maybe some other people on the site know a trick or two and could show you....!!!

Strictly speaking, we would have to have a restricted domain on the original function since it isn't one-to-one.....

However, here's what WolframAlpha has .......(the red graph is the original and the blue one is the inverse)

We would want to write it as:

f^-1(x) = (x+2)/2 ±(1/2)√(x)√(x+4)

Well he probably did get it then. Ask him maybe. 

thats right ! and the owner wont eat the pills too and the years will pass and pass and one day the bottle will become an antique one and the pills would just rot inside the bottle (yuck) ! so whats the use of buying such a bottle of pills which doesnt let itself be eaten just becoz ur happy u bought such a "costly " pills bottle !

Im on a little phone just warning you

I would have thought that one thread with one major section, like algebra, per post.

Leave first page for instructions and odds and ends. 

Nearly all addressed

Posts should be elsewhere.

Id want the address of the original include d in the first page so it does not disappear. 

More later.

Thanks

It is in my conversation, though.

That's a good point!

You might set it on a trophy shelf for that matter!

if a bottle of pills would cost 8000 then it shouldnt be kept in a glass cover as a show piece for the buyer wouldnt eat the pills but show off the bottle which costed 8000 to him !lol!

Haha, my bad.

I read it like, "A bottle of pills that has 30 pills in it costs 8,000, how much is the cost per pill?"

I didn't mean to pile one more thing on guys' plate, you guys do quite alot!

I could try to make a "cleaner" page for this information, but like you said only one person could edit the post, so would you want to be this person, or would you want me to be the author? If I were the author I suppose you could tell me if you saw something you'd like in it, and I could add it.

I'll commit to making a new page for this though. I am currently on a 22 hour car drive, so I have plenty of time to waste! :)

Do you guys like the idea of the one big post for the information, though?

im sorry NinjaDevo but 30 bottles of pills cost 8000 not a single one !

$ 8,000 for one bottle of pills?!? Those are some spendy pills!

If ifs not in your conversation list I think it is a fair bet that he never received it.

this is an easy question so i want u to try it out urself ! so we have 30 bottles which cost 8000 and now we are to find out the cost of one bottle ! now if 30 bottles cost 8000 then we can simply find the cost of 1 bottle by just deviding both these amounts , like 8000/30 ! as i said u are do some of it urself so now ive told u this and u r just to devide it ! for a tip to do the division a bit quicker cut each zero of ech number like;

8000/30 so 

=800/3   does this make it easier to devide ! so now i hope and also believe u can solve it urself , the rest of it!

HINT; Use the calculator of this site !

When I go into the "conversation" between me and CPhill, it does say I sent him the question.

Maybe we should ask CPhill, maybe he just thought I'd figure the question out myself, so he didn't answer.
