Algebra Is Your Friend

16 May

Today, I accomplished something even my Honors Algebra teacher couldn’t.

I graphed Batman on my trusty TI-83, Bessie.



It took me literally 45 minutes to get it right. I used three different equations before I got the desired result. If you want to give it a try:

Equation #1 (failure):

Y1 = 1.5sqrt(-abs(abs(x)-1)*abs(3-abs(x))/((a­¬bs(x)-1)*(3-abs(x))))(1+abs(abs(x)-3)/(­a¬bs(x)-3))sqrt(1-(x/7)^2)+(4.5+0.75(abs­(x¬-.5)+abs(x+.5))-2.75(abs(x-.75)+abs(x­+.7¬5)))(1+abs(1-abs(x))/(1-abs(x)))

Y2 = -3sqrt(¬1-(x/7)^2)sqrt(abs(abs(x)-4)/(ab­s(x)-4))

Y3 = abs(x/2)-0.0913722(x^2)-3+sqrt(1-(abs(a¬­bs(x)-2)-1)^2)

Y4 = (2.71052+(1.5-.5abs(x))-1¬.35526sqrt(4-(­abs(x)-1)^2))sqrt(abs(abs(¬x)-1)/(abs(x)­-1))

Yeah… there are some cowboys in that one. Number two is a bit better.

Equation #2:

I like this one because it’s colorful. The different colors are different Y=’s. Go for it!

Equation #3:

Number three require you to change to “PAR” in mode. These are the parameters:

X1 = {1, -1}(2.5sin(.5T) + 4)
Y1 = .7T + 2

X2 = {1, -1}(7sin(.5T) + 4)
Y2 = 1.8T – 1.5π

X3 = {1, -1}(cos(.5T) + 1)
Y3 = 2sin(.5T) – .1T2 – 3

X4 = {1, -1}(.25T + 2)
Y4 = .5T-1 + 2

X5 = .6T – .6π
Y5 = .75sin(.5T) + 5

X6 = {1, -1}(1.4cos(.6T) – 3.4)
Y6 = 1.7sin(.6T) – 3

And that was the successful one!

I think because I did this, I shouldn’t have to to my homework tonight… eh?

Algebra’s your friend, mate!


The Calculator Gotham Deserves

Vitamin Deficiency, Sad Things, and Benedict Cumberbatch

8 May

Today I am depressed. I’m pretty sure I failed a pop Algebra quiz on probability.

Is it my fault I’m not familiar with playing cards? No. I don’t know how to gamble. Shouldn’t that be a good thing?

I also am dying from a Vitamin deficiency. My hands are killing me, my head feels like its being stabbed with a rusty blade, and my bones are imploding. I’ve been out of vitamins for three days and I feel like death. Seriously, what did I do to deserve this torture?

Another super depressing thing: My Theology teacher’s grandson in in hospice after years of battling cancer. He is very young and it is very sad for all of us. A link to his mother’s blog: http://supermacconnor.blogspot.com/

In funner news, Benedict Cumberbatch is the most amazing person on the planet. For the last few years he has been my favorite person on the planet. If you live under a rock, this is him:

He’s fabulous, right? He plays the title role in BBC Sherlock and is John Harrison in the new Star Trek movie. His voice is like a jaguar hiding in a cello and is possibly even more socially awkward than I am.

Oh… Benedict…


Anyway, today has been rough. School is out in a little over a month which brings me some joy.

Update: 3:52 pm

It is now raining. But it’s in the seventies. This weather is awful. I seriously want to puke. Alaska must be beautiful this time of year.

I’m going to tell you a story.

Once upon a time…
My life was not full of the funny beautiful references and jokes that brighten up my day well.

There was also a time where I wasn’t on Pinterest.

In history we were talking about the Puritans and I remembered this picture:



I laughed and laughed in my head.

Whenever I think of this pin,


I laugh because King Henry was a crazy man with a decaying and infected leg.

Well… Enough chatter for now!

¡Adios amigos!
