Get a nice one, like TI-84/89/n-spire.
#152 Re: Help Me ! » Learning Trigonometry » 2014-07-17 02:19:47
Not necessarily, but in many problems you do.
#153 Re: Help Me ! » Learning Trigonometry » 2014-07-17 02:03:37
Maybe try TIMSS next year? Learning this here and there won't help a lot.
#154 Re: Help Me ! » Learning Trigonometry » 2014-07-17 01:02:44
But I shouldn't get in there yet?
Precalculus - Concepts throughout functions a unit circle approach to trigonometry.
If you are done with algebra (from Sullivan's other book), you can go to Precalculus by Sullivan.
You kind of have to go through the chapters mostly in order.

Precalculus by Sullivan explains everything very well.

#158 Re: Help Me ! » Algebra I » 2014-07-14 08:28:55
Yes, it's correct. Just plug in the values for x and y in the equations to check.

I do, especially because there would be way more goals. 
#160 Re: Dark Discussions at Cafe Infinity » Brazil 1-7 Germany » 2014-07-14 01:41:58
I actually wanted to see Germany 3-0 in penalties.
#161 Re: Dark Discussions at Cafe Infinity » Brazil 1-7 Germany » 2014-07-12 12:35:22
Netherlands 3 - 0 Brazil

Welcome!
#163 Re: Puzzles and Games » FUN add 28 game! » 2014-07-10 01:50:55
I think she wanted to start at 28, but she wrote 28! instead of 28.
#164 Re: Dark Discussions at Cafe Infinity » Brazil 1-7 Germany » 2014-07-09 01:47:51
Thanks.
#165 Re: Dark Discussions at Cafe Infinity » Brazil 1-7 Germany » 2014-07-09 01:07:32
I don't know some rules in soccer/football either, but as long as you know what a goal is, it's fun to watch.
I'm not feeling the best today. Going in the wheelchair hurts too much. How are you doing?
#166 Re: Dark Discussions at Cafe Infinity » Brazil 1-7 Germany » 2014-07-09 00:53:35
Great stuff from Germany.
I think you should watch the final for sure.
#167 Re: Dark Discussions at Cafe Infinity » We are the universe experiencing itself. » 2014-07-04 13:57:57
What does "experiencing itself" mean?
#168 Re: Maths Is Fun - Suggestions and Comments » Separation of Variables » 2014-07-04 13:56:20
Looks pretty good!
#169 Re: Maths Is Fun - Suggestions and Comments » Solution of First Order Linear Differential Equations » 2014-07-04 13:54:04
Great!
#170 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 04:19:40
That's every discipline.
#171 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 03:50:11
And bobbym's correct yet again.
I was talking about the World Wide Web.
#172 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 03:48:05
I believe CERN created something called ENQUIRE in around 1989 or 1990.
#173 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 03:43:29
I think bobbym is wrong (an extremely rare sight!).
#174 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 03:36:43
I'm in support of the LHC and many of CERN's projects.
#175 Re: Dark Discussions at Cafe Infinity » Has the large hadron collider destroyed the world? » 2014-06-27 03:29:37
Sorry, I was talking about the whole news coverage of it being nonsense.
They can't really explain it to the public...
