Bababa ba?

Quiz time!

Take the quiz here.

And I thought I’d either be the Science/Math or Gamer/Computer nerds. Hahaha. It had questions like, “how many hours a day do you play online games?” (uhh 1-2?), “how many hours a day do you spend surfing the net?” (3-6!) and “how many hours to you play videogames??” (1-5 hours!!).

Lol.

It was my first summer afternoon. Hahaha. But instead of catching up on what I missed most the past sem (read: sleep), I went shopping. Hehehe.

You see, my iPod earphones conked out a long time ago. So, I got them replaced with a pair of cheap Philips earphones, just to fill-in for the job of providing me with my music. After a few months of “rigorous” use (jogging, commuting, etc etc), as expected, they conked out too. Good thing I was already able to save up for a pair of rocking earphones.

After 10++ hours, 12 pages, 5 excel worksheets, 6++ Yahoo! chat windows, 2 packs of Skyflakes, 1 can of Hot and Spicy Century Tuna, I finally finished that effin’ Stat115 take home exam!

Yebah!

I can smell the sweet scent of summer already.

Oye, oye, oye!

Sleep, finally.

Tapos na ang Math.

Stat naman.

My past few entries have been the nerdiest, I believe. Hahaha. I apologize.

Masaya kasama ang RHP! Hahaha. Tagaytay na tooooooh

I was studying for my Math53 finals (eep) tomorrow when I came upon a function that has a non-existent limit (positive infinity from the right, negative infinity from the left: a vertical asymptote).

And then Mean Girls comes into mind. So, nerdy-ness kicks in and I rushed to Dad’s laptop to search for the limit-less function from Mean Girls fame.

So, this is what I found:

Upon initial inspection of this function, one would notice that finding its limit is not an easy 30-second task. Substitution would yield an indeterminate limit, with a form of 0/0. So, how did the Mean Girl get it in less than a minute? Hoooow?

So I began to solve for the limit. What I first did was be to use l’Hospital’s rule, because the initial limit was in an indeterminate form. It would then yield

But when we substitute 0 for x, we would get -2/0. So we need to check the left and right hand limits for us to be able to conclude if the limit exists (as either positive or negative ∞) or if it does not exist.

So…

The above limit would yield a limit of +∞ while the limit below gives us a limit of -∞.

So, after a lot of computations (and much time), we can finally conclude that the limit does not exist since the left hand and right hand limits are not the same.

Madaya lang talaga si Cady kaya niya nasolve yun. Di kaya ng powers ko yun!

Oh my gulay. I need a life. Pray for my finals tomorrow.

UPDATE: Hindi ko pala kinailangang mag l’Hospital’s. Hahaha. Kaya palang gawin yun sa simpleng pagsubstitute ng maliliit na values from the left and the right of 0.

From Peyups.com: math profs to avoid

sabi ng mga kilala ko, wag daw kunin sina wee at wong.
si wee daw, out of this world yung questions sa exams.
si wong naman daw, sa simula lang magaling magturo.. pag gitna hanggang huli na.. good luck na lang daw.

Hay. How true. Kung bumagsak ako ng 53… ewan.

Why, oh, why do my profs give out of this world questions in their exams?

There’s Math53
and Stat117
and Kas2.

Buti pa ang MuL9.

I just woke up from a 3-hour nap, and, ang sakit sakit sakit sakit sakit ng ulo ko. Yung tipong sakit ng ulo na parang sakit ng ulo kapag may hangover ka (minus the nausea). Feel ko talaga nag-lasing ako kagabi. Well, kasi ba naman, 4 hours of sleep plus 5 straight hours worth of exams, putek. Ito na ba ang feeling ng wala nang utak?

I was chatting with an incoming UP freshman, this morning, while writing the previous entry (rather than studying for Stat117 ;p). She was asking about a lot of things, from pre-enlistment, to subject choosing, to registration and enrollment and stuff.

Memories. Haha. Around a year ago, it was I who was asking such questions (hi Ate Joy! Hi Patrick!). Hahaha.

Wow. Freshman year is almost over. Ang weird ng feeling. Parang kailan lang _____ (insert multitude of freshman memories here).

Mamaya na ako mag-rereminisce. Hahaha. I miss my online social life. And may Stat115 take-home exam at Math53 finals pa kasi, so hindi pa talaga tapos ang lahat.

Invalid argument

If I do not study in Stat117 then I will fail the course.
I studied in Stat 117.
Therefore, I will not fail the course.

—

Let p: I studied in Stat 117
q: I will fail the course

The above argument states that

~p → q
p
therefore: ~q

But, as the title of this entry says, it is an invalid argument. There are no Rules of Inference that state that the conjunction (~p => q) and p will leave us with ~q. Thus, even if I studied, I cannot logically conclude/predict that I will pass the course.

The following truth table further disproves the above argument

But, if I did not study, the second premise would be modified, and so

~p → q
~p
therefore: q (by Modus Ponens).

So yeah. Because Modus Ponens says so, I will fail the course. :p

And I computed that the chances of me perfecting a set of 5 multiple choice questions, with 4 choices each, just by guessing is 1 out of 4×4x4×4x4 or 1 out of 1024. So what more if the exam is composed 50 multiple choice items?

I really should be studying right now. But, but, but, I really really really miss this blog.

I have two exams tomorrow. Stat117 finals @ 9-12, Math53 5th long exam @ 11:30-1. Galing noh? Overlapping. It’s a good thing mabait si Sir Wemer.

Onti na lang, BA. Onti na lang.

Birthday’s in a week and a half. Haha. Ang tanda ko na.

I EFFIN’ HATE 2-PAGE SINGLE SPACED ESSAYS

After having a wonderful first sem in my freshman year, a bad second sem follows.

This second sem, for me was very critical. This was the time that my parents gave me the blessing to shift to BS Applied Physics, my senior year high school dream course.

This didn’t come as easy news, however. Knowing that I’d be shifting eventually, I lost the drive to study for my Stat classes (Stat115 and Stat117). I started not to care about these subjects. I now study to pass, unlike last sem where I studied to excel.
So I computed all the possible grades that I’d need to shift to Applied Physics. I would be needing at least a 3.0 in my Math and my 2 Stat classes. So yeah, I just have to pass these classes. Hahaha. Talk about mediocrity.

I just quit studying for my Stat117 exam later. In wrapping up my studying, rather than reiterating the formulas (and that cursed binomial theorem) in my head I computed what possible grade I might have if I would have a score of around 50% in later’s exam. I estimated around 2.5-3.0. And since I never missed Stat117, i have a -.25 bonus, so the estimate goes up to 2.25-2.75.

Whatever happened to MAGIS? :p

Anyways, this sem, I only had 2 great subjects (PE2 Streetdancing, MuL9). The others, were, err, not so good.

I’m having trouble in Math53, my Stat115 is a bit off, my Stat117 is way off (see above), and Kas2, hay, let’s just not talk about Kas2.

So goodbye to landing College Scholar or University Scholar for this sem. Goodbye to Cum Laude standing.

And oh, I’m gonna die Monday. I have Stat117 finals at 9-12 and I have a Math53 exam at 11-something. Sir Wemer said I could just make habol. Spaghetti na siguro utak ko pagkatapos nun.

PS: Another reason why I think I lost my drive to study for Stat: Microsoft Excel. Remember the long nights of graphing and solving and stuff? With a few clicks the 3++ hours would just be 30++ minutes.

Kung bukas makalimutan ko ang binomial theorem ganito na talaga isusulat ko:

My brother, J Angelo sent me a YouTube video of Pia (my niece/goddaughter) dancing in their Moving Up ceremony. They were dancing “I’d like to Teach the World to Sing.” It was cute, as in C-U-T-E, cute! Hahaha. Pramis. I never imagined 3 year olds being able to dance like that.

But I can’t help but think that if Pia saw this video a few years from now, she’d burst in laughter and say, “OMG, I can’t believe I did that back then!”

Last night, in Chax’s debut, they played videos of her childhood. She was dancing, singing, and singing and dancing! Everyone was aww-ing and laughing at the same time.

I was a bit envious after watching the said videos. My parents weren’t able to chronicle my childhood through moving pictures. The only moving pictures that I have left are the ones in my memories. And I can’t see myself through it! Darn :p

But then again, I have something to be thankful for.

You see, my Mom has this habit of writing random stuff about us, her children. She wrote a few articles about us to either contribute in magazines and newsletters, or just to keep as memories.

Just recently, after releasing her 8 year-old article Raising Stress-Free Children, she had “opened her treasure chest of mommy moments memories” to share amongst her friends in the blogosphere. Memories gushed in once I read the latter entry. It seems like these memories were pushed waaaay back in my mind. Mom’s writings were memory refreshers.

So, my parents weren’t able to video me dancing the “Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini Song,” or me singing and dancing “Jingle Bell Rock” while wearing gigantic shades, or me singing in Ateneo Grade School’s farewell mass, or even when I *shudder* played lead role in the play Agyu. But somehow, Mom was able to write some things down. :)

And for that, I am very thankful.

I dunno. Written chronicles, for me, are kinda different. ^_^

(maybe that’s the reason why I blog. XD)

I received this comment on my previous post that my blog was nominated in Da-Blog’s Week 1.

Whoever you are who nominated me, thanks. ^_^

So just go to the Bright Eyes blog and look for the poll thingy, and vote for my blog, “Bababa ba? O aakyat?”. Thanks! ^_^

Mom was working on this research thingy that needed some statistical analysis and legal help. So naturally, for the statistical analysis part, she asked me if I could do it for her.

At first I was reluctant, even though money was involved. She asked for help when I was in a party, so, what she texted seemed gibberish at that time (booze, anyone?). I sent her numbers of StatSoc seniors who I felt were up to the job, but alas, none but one replied. I forgot (booze?) that today was StatSoc’s Challenge Day, so most of them were unavailable for the moment. But Mom’s project was due on Monday!

When I got home, I checked out why Mom needed a statistician. She then showed me the data and what how it was needed to do with it.

After scanning the data, I told Mom, “Ma, I can do this.” (epekto pa rin yata ng booze)

And with the help of Microsoft Excel, we toiled for around 2 hours, computing for the descriptive statistics, computing for the confidence level, and then finally, interpreting the data.

While I was solving, I realized that if I don’t shift courses now, this is what I may be doing all my life until I resign/retire/die.

And that, I didn’t like.

I was joyful when I finished the project. I was a few hundred pesos richer, why wouldn’t I be happy? But, for me, doing something like this everyday with a pay of only around a few thousand pesos a month, is not worth it.

Remember how I used to rant about corporate work being possibly too repetitive and boring? Here I go again, ranting. Hahaha.
