I think it is really interesting. It looks much more difficult than it really needs to be. और पढ़ें ..

Remeniscing - a little historical humour.

I just found this old post that some of you, who have been around for a while, might find amusing.

Miltonjlopez:
What percent of 24 is 12?

You write it as a fraction and then multiply by 100 to turn it into a percentage.

12/24 * 100 %

--------------------------------------------------
What is 12 / 24 as a simplified fraction?
What is 1/2 of 100
Maybe this will help as well.

ddavis1999:
(sqrt(3)-4)/(sqrt(3)+4)

To simplify this you have to multiply top and bottom by the conjugate of the denominator. That is (sqrt(3)-4)
That will rationalize the denominator.
You will then need to simplify anything that you can to leave it in its most presentable state

Hi everybody,
Another busy day. I think that Rom and 'Someone' answered the most questions. Thank you for all your efforts.
Hi, someone, It is nice to meet you. I don't think that we have met you before, It would be really nice if you joined up properly. There are a number of advantages but I don't think that I will go into them all now.
There were many other great answers from jyotig, Letchersavanna, dealor and a number of 'guests' A big thank you is given to all of you.

* I also received a nice thank you from a guest. It is always nice when people show appreciation.
* Happyfeet has started her? own snark thread named "Why so hard" A couple of people have joined in the fun, including myself. If you don't like insincere threads I suggest you stay clear of this one.
* There was a new 1+1 post and I am please that everyone ignored it. That particular snark is getting a bit tiresome.
* There was one crude post. I was tossing up whether to say anything. I think that if it had been very near the top I may have, but it had already moved down the list and if it had been responded to, that would have put it back at the top again. If it is left alone it moves off the first page quicker. Did I do the right thing or should I have said something. Any thoughts?

* I used the display feature of the web site calculator today for the very first time. It was very appropriate to the question. Thanks Reinout-g, if you had not brought it to our attention it would have continued to be an ignored resource (by me anyway).

I would like to suggest that people look at their own answer posts at the end of the day. Sometimes they have been added to by others. There may have been a problem or someone may be trying to communicate with you.
Also, I think that looking at other people's posts is always a good idea. You may learn content or you may get alternate ideas on how to present that content. I have learned a lot by watching others.
That's it,
Goodnight all,
Melody.

AlexaZ:
How do I find trig rations for each angle?

Do you have trouble remembering them.

SOHCAHTOA (like the volcano)
sin = 0pp / hyp
Cos=adj / hyp
Tan=opp / adj

or
Some old hags
can't always hide
their old age.

the first letters have the same meaning as above.
