This is not a trig question. In fact it is not a question at all.

Look for a number that goes into the top and the bottom and divide them both by that.

I've been learning some cool stuff!

How do you find the greatest common divisor of 2 numbers if the numbers are large and you don't want to take forever to do it?

Well, you use the Euclidean Algorithm.

This is how it is done . It is really easy when you get the hang of it.

Take a look at this.

agalya:
54.7 can be rounded as 55 or 54?

Hello agayla,
If you want to round 54.7 off to a whole number it will be 55.

the 7 is used for the rounding. Any number 5 or bigger than 5 will force the next number up.

for example I am going to round each of these off to the nearest whole number.
63.9=64
1.08=1 (because the next digit is 0)
12.5098=13
56.7 = 57
19.499 = 19
999.78 = 1000
14.5 = 15

Hi all,
I am in a good mood because i just did the puzzle question (math by gutierrez) totally by myself.
Reinout-g said it was likely to cause him sleep deprivation, and I like Serena resorted to Wolfram|alpha.

Alright, enough about me.
There were many great answers given today by Rom, I like Serina, Not a homosapien, Blogganta, Selina Marie, Justin,Amos Tomlin, MissRaevalynn.
A big thank you to all of you.
I also saw a nice thank you post from Zamarronics (for DavidQD). Thank you on David's behalf.

It appeared to be unanimous that -x ⁿ should always be interpreted as -(x ⁿ). I was troubled about this yesterday.

The number of questions that are being posted appears to be growing exponentially. I did expect this to happen but that doesn't make it any easier.
I am thinking that perhaps we could more often refer students to a learning resource like a you tube clip or a mathsisfun site. I don't want us just to do a student's homework. I think I caught someone today posting a series of log questions. Maybe, with the more advanced students, we could start requesting more interactivity. With the younger ones we could do a similar problem rather than the one they present us with. I want the site to be very friendly but some of these tactics might discourage some of the people who are using us in a not so desirable way. I personally am answering far more questions than I really want to. Rom answered a great many today as well. It leaves little time for other things.
I am probably giving mixed messages (to people who answer questions). I am sorry, I am trying to feel my way.

There is a new post running asking for people to add ideas and comments relating to all aspects of the forum. Please use it. I really do want your input
On a very positive note there appears to be a greater number of students posting answers. This is exactly what we want. Thanks folks.
Melody.
