Salvation For The Masses

(5)
Posted at 10:47 pm by Miss Loi in Miss Loi's Exam Papers

Under a pale grey sky he stood, by the busy pedestrian crossing in front of Bras Basah Complex, oblivious to the passing group of cutie schoolgirls as he reflected on yet another wasted trip there in search of those elusive Ten-Year Series.

In a dark empty classroom she sat, hanging her head in despair after being outscored yet again by that foreign cyborg in the latest maths test, as she desperately sought for more difficult and trickier sets of questions that will hopefully lead her to victory in the next test.

In a chaotic study room he raged, with eyes like those of a madman as he screamed for more to satisfy his insatiable thirst for math questions, having finished every known assessment book that was ever published, plus all the Ten-Year Series from 10.000 B.C. to 2008 A.D.

And on a messy desk she wept, wondering when will she be able to make sense of the maths questions, despite going through them a many times and still getting them wrong every time.

All of them had a wish in common ...


Meanwhile, the skies above were suddenly filled with a large flock of white doves, carrying the Word to all corners of the land - that THEY are finally here ...

The Night Nothing Stood Still

(11)
Posted at 10:47 pm by Miss Loi in A-Maths Questions

The howling started at 11pm on Wednesday night, filling The Temple with an air of fear that was quickly followed by eerie rattling sounds coming from the roof above, as if its tiles were being systematically peeled away by whatever's behind these ungodly noises.

With thoughts of being in a scene of a Korean horror flick (where the actress usually dies) flooding her mind, Miss Loi decided to abandon the Kinematics question she was doing and quickly closed shop for the night.

The curls of her hair were instantly straightened by a mighty gust of wind the moment she stepped outside the Temple Gates, to be greeted by an extraordinary scene unlike any she had ever witnessed: leaves, twigs, plastic bags and whatever <1 kg were strewn everywhere as gale-forced winds lashed through Novena.

Fallen Tree

Closing her agape mouth just in time to prevent any unwanted debris for supper, Miss Loi recovered her composure and tried to make a dash for her car under the deafening roar of the wind.

Oh it was not a pretty sight as her hair parting constantly changed directions as the wild tempest battered her from all directions - with flying twigs that threatened to scar her precious face, and NTUC plastic bags & the odd flying underwear that threatened to smother her at every turn - all while being mocked by Ivy Lee in brochures blown from the neighbourhood slimming centre.

When she finally hit the road on her way home (albeit with a new hairstyle), she found to her dismay the roads perilously littered with leaves and branches, with huge fallen trees blocking her way :(

Miss Loi's car first passed a big tree located along the way at a fixed point O at a speed of 210 m/min.

Assuming that she moved in a straight line and that her acceleration a m/s2 at t minutes after passing O is given by a = 60t − 240,

  1. Calculate her speed at the second minute.
  2. Given that she had to turn back immediately to the direction she came from upon encountering a fallen tree, find the value(s) of t when she had to turn back.
  3. If the big tree at O was felled by the wind at the tenth minute, will she be able to pass it before it fell? Calculate the total distance she would have travelled in 10 minutes.

To further what's being taught in its EMaths counterpart, AMaths Kinematics introduces the terms displacement (s) and velocity (v) which may be very loosely considered as distance and speed involving direction respectively.

So instead of that headstrong cyclist/car/train in your E-Maths Kinematics who somehow lost its reverse gear and end up moving in only one direction, you'll find in AMaths modern cars like Miss Loi's (or more commonly 'particles') that can move back and forth like a maniac in opposite directions, with the following relationships between displacement (s), velocity (v) and acceleration (a):

s = int{}{}{v} dt doubleleftright v = ds/dt
v = int{}{}{a} dt doubleleftright a = dv/dt

P.S. Most of the above story is true, except the part on the flying underwear. Maybe Mother Nature was trying to tell us something on Earth Day 2009?

How To Win Friends And Influence People

(8)
Posted at 11:43 am by Miss Loi in Study Break

Admittedly, Miss Loi has been on a bit of a blogging hiatus lately (sorry will get back to replying the comments here later).

She's been slogging away at The Temple, busily juggling a multitude of tasks like replying emails and assuring kan cheong parents over the phone of their kids' progress and 打小报告 on their misdemeanours in class, and applying the finishing touches to her Sec Three/O Level exam papers, whenever she's not preparing students for their upcoming Mids.

And on one such afternoon yesterday, she had just completed compiling her Mensuration chapter of her topical exercise, and was about to take a break with a new episode of the TVB drama when she was startled by the sudden appearance of a man at The Temple Gates.

Miss, interested in this mobile phone charger? Can charge your phone on the move, no need to plug into the wall one.

*shakes head*

What about this torch? Very long lasting one. Interested?

*shakes head*

Convinced that Miss Loi is neither a fan of his super duper wall-less charger nor his eternal torch, he began walking towards the inner chambers of The Temple, convinced there were far easier prey that lie within.

Umm ... sorry you're not supposed to sell your stuff here.

The man looked offended.

Why can't I sell here? This is an office. It's a place for business. I'm doing business, and you're doing business too. So why can't I sell here?!

*stunned for a moment*

Anyway, you're not supposed to sell things here ... please leave now.

The man went hysterical.

What is your problem?! Why are you so aggressive? WHY ARE YOU BEING SUCH A RUDE CUSTOMER?!!!

With that, he stormed out.

And so it came to pass that on this day, after all the years of reprimanding students without mercy, the mighty High Priestess finally found herself on the opposite end of a scolding, in her own office, by a spurned trespassing mobile charger cum torch salesman.

P.S. Sorry, just had to get this out of the system :? Alright back to work ...

頑張って!!!

The Great Tiger Prawn Massacre

(21)
Posted at 10:00 pm by Miss Loi in A-Maths Questions
如有雷同纯属巧合

As reported previously, Miss Loi has been working late nights (yes, yes, yes you'll hear about them real soon).

Tiger Prawns
Scene from The Great Tiger Prawn Massacre
[Source]

When strange sounds were heard coming from the direction of her tummy last night, she finally decided to end the day's work and drove to the nearest hawker centre (from The Temple, Novena) that was still open at this late hour, for a sinful late night dinner to appease her stomach.

There was barely time to savour the sweet aroma at the smoke-filled hawker centre when she was forcibly promptly ushered by a helper to a table beside a BBQ seafood stall, where rows of tiger prawns were on display and were being advertised at a price of $10 each.

Feeling extremely hungry by now, Miss Loi succumbed to the juicy sight of these succulent prawns. And in a classic don't-care-3-7-21 (不管三七二十一) rash moment, she decided to throw her entire dieting plan to the wind by ordering a whopping total of FOUR tiger prawns.

Upon completing her messy massacre of the prawns, it was Miss Loi's turn to be massacred when a bill of $120 was presented to her by the stall owner.

When questioned, the owner shrugged and said

小妹! These are premium prawns! $30 each! Bigger, longer and better than those $10 ones!

Miss Loi, however, was adamant that wasn't the case.

But they look exactly like the $10 ones.

The owner became agitated.

小妹! WHAT'S YOUR PROBLEM?! LAST TIME WE CHARGE BY WEIGHT AND THOSE *BEEP* ANG MOHS CAME AND GIVE PROBLEM! NOW WE CHARGE BY LENGTH AND A SEXY GIRL LIKE YOU COME AND GIVE PROBLEM!

YOU SAY WE OVERCHARGE YOU - WHERE'S YOUR PROOF?!

With that he took a $10 prawn from the display and placed it, in an oblique manner, beside Miss Loi's last unfinished prawn on a dish.

NAH! SEE?! YOUR *BEEP* PRAWN IS MUCH LONGER! PROVE IT TO ME IF YOU THINK IT'S NOT!

When Miss Loi tried to align the prawns properly, four well-built men (who looked to be in their 40s) appeared from nowhere and blocked her access to the dish.

OI! *BEEP*! WHO SAY YOU CAN TOUCH?! I ASKED YOU TO PROVE NOT TOUCH!

The prawns, whose lengths are represented by the lines ABC and ADE, are placed in such a way that ABC and ADE are secants of the circular dish as shown in the diagram below.

Given that BC = DE, prove that AB = AD.

Tiger Prawn Plane Geometry

YOU SO SMART YOU COME AND PROVE LAH! *BEEP*! YOU THINK WE HAWKERS GOOD TO BULLY IS IT?! *BEEP*! IF YOU CAN'T PROVE DON'T EXPECT TO LEAVE THIS PLACE TONIGHT! MUAHAHAHAHAHA!!!

*BEEP* *BEEP* *BEEP* *BEEP* *BEEP*

Given that that her 阴阳眼 Of Plane Geometry is refusing to work OT since it's already late at night, and that this question is similar to an evil tricky one contributed by a student (actually this IS the question, minus the prawns), and that she's being surrounded by more and more well-built men (who looked to be in their 40s), can you please help Miss Loi (with the aid of the sheet below) prove the above and escape from the hawker centre? :(
