Today in Math. :/

Today in my math class we learned how to find the magnitude of a vector. We also learned how to find the direction of a vector.
To find the magnitude of a vector you use the formula:

So, if you have two points on a line P and Q and P's coordinates are (1, 2) and Q's coordinates are (5, 5), you would plug that into the above formula to get:

<5> = <4,>

You would then use the distance formula to find the magnitude:

The square root of (5-1)[Squared] + (5-2)[Squared]
=
The square root of 25 or just 5.

So the magnitude of ray PQ is 5.

To find the direction of a vector you take the difference of the x's and the difference in the y's and divide them. Take that answer and find it's tangent.
On a calculater press the 2nd button, then tan. Tan[Negative 1] should come up on your screen. After that put in the answer you got from dividing the x's difference and the y's difference. You now have the angle that the vetor is traveling in.

[P.S. I hate math. I just thought you should know.]

It's alive. :]

My blogger has decided to freak out on me. Well, either my blog or my computer has.
Either way this is a post to make sure that it didn't die. [:

--------------------------------------

Alright, it didn't die. :D
Today was a good day, sorta. Well, it was mainly good. I had a bad dream last night so that made the morning kind of bad. But the rest of the day was good.
FIRST PERIOD; We watched a movie. It was funny, although I don't think it was supposed to be. I have a weird sense of humor, that should explain it. Haha.
THIRD PERIOD; He checked our homework and went over some stuff that I actually understand. I finished my homework in class.
FIFTH PERIOD; We watched a documentary about heart disease and crystal meth. They're separate videos, not the same. Hah. I texted my friends when they were sitting right next to me. We made fun of some of the things in the video.
SEVENTH PERIOD; We watched 'Energy Wars', it was boring, so I slept a little bit. But before I slept I ate pizza and had Hawaiin Punch. It was very good. :] Anyway, after I woke up me and my friends drew stupid pictures.

Tell me about your day. [:

Random. :]

I'm supposed to be doing geometry homework. I'll do that after this though. I just like that picture and I don't want to just post a picture, so I'm writing. Yupyup.
But yeah, yesterday I went to the movies. I saw Taken [again] and Push. Push was actually good. I wasn't sure if it was going to be or not. But I liked it. The black guy was cool. Hah. I don't know his name, but I've seen him in other movies and he's awesome. Yup. :]
This is a pointless post, so if you get bored just stop reading. Lol.
Hmm, I think that picture could be a bit brighter... That's kind of depressing. Well, no it's not, but still.
I'm done trying to think of things to say now. :P
Peace. <3
