## [0881] Killing Fields

└ posted on Thursday, 27 April 2017, by Novil

The *Sandra and Woo* adventure game developed by Feline Fuelled Games is finished and will be released in exactly one week, on Friday, 5 May 2017! Find out more in the following **blog post**!

**Question 5:** Come here, Sandra! Take my hand!

**Question 5:** You only need compass and ruler to solve me!
**Sandra:** … Could it be? A ray of light in this sea of darkness!?

**Question 5:** … And inverse trigonometric functions!! HA HA HA!
**Sandra:** AAAAAH!

Missingno. Masterwrote:Given some of the struggles I occasionally had with math in high school… I’m suddenly glad I rarely remember dreams. Scary stuff!

@ Nachum:I believe that’s a beta, not an eszett

GO! GO! POWER-MATHERS!

And now Landon comes in and saves everyone. Somehow.

Oddly enough, this reminds me very much of my nightmares that were high school math. The one subject I could not overcome . . .

Cloud desperately wants to save Sandra, but unfortunately he’s rooted to the ground.

Thank you. I’m here ’til next Tuesday. Try the veal.

@ Markas:Any science using math is treacherous. In yesterday Physics test, when calculating resistance of resistors in parallel setting, I forgot to revert fraction and it cost me 25 of 100 points.

Ah yes … memories …

But the rewards, once you get past the initial hump of understanding, are immense.

I see someone was inspired by Assassin Classroom.

Robin_WHwrote:The upside is that blowing a test by that kind of mistake can really pound the information into your brain. Failure today, but knowledge forever. 🙂

Could you you maybe do me a favour and sync up Sandra & Woo and Gaia again pls?

I’m just glad I didn’t see any tanh. I hated hyperbolic trig functions in high school.

More of these please, this is hilarious.

@ myth buster: Yeah Assassination classroom was what I first jumped to as well 😂@ AmbiguousMouse:okay, that’s just an overstatement my good sir, come on, kids are here as well, i think, dunno?

@ Ezra Dudden:Darn auto correct it’s cost of 7. Not closet. Sigh.BTW the square

rootof that tree is 50.2.Ah, back during my college calc days… I would have been seen standing atop a hill of bodies, graphing calculator in hand, bloody but victorious. My classes got worryingly intense at points but I never got less than a B in any class. I was a powerhouse of a student for sure.

One time, an instructor even gave out a bonus credit problem that was flawed, and I used a calculator to prove that it was unequal, and he told me “Calculator’s wrong”. He stubbornly held this viewpoint until the time to submit it came along, when he finally had to admit that the problem was incorrectly written in front of the whole class.

As for Cloud, someone just needs to cast Raise… to fractional power.

@ Grayson Judd:no, i say it is around precalc maybe AP calc for American student, and about 8-9 th grade math for Chinese students.

Oleg Oshmyanwrote:That is all together wrong. In a field of real numbers, following axioms of a field, 1/x is defined as (1/x) * x = x * (1/x) = 1. Suppose, there exists an answer to 1/0, so there exists some y such that y * 0 = 1. Then 2 = 1 + 1 = (y * 0) + (y * 0) = y * (0 + 0) = y * 0 = 1. Contradiction. Therefore, no such number exists. Saying “it’s infinity” is not an answer, because we clearly cannot perform as basic operation as addition on whatever it is. If an answer to an operation with real numbers is not a real number, the operation is undefined. There is something to be said about extended reals, but that’s a completely separate topic. Saying “algebras exist where you can divide by zero” is about as useful as saying that “algebras exist where 1 = 2.” So we’re back to real numbers where you can’t divide by zero. End of discussion.

Anyone remember imaginary numbers? I thought they were fun to solve.

Don’t see them very often, occasionally dealing with electronics they show up.

@ Stungun:You were allowed to use graphing calculators in math tests? We weren’t even allowed to use simple calculators in math when I studied. That is except for one test and that only because doing transcendent functions by hand to six digit precision is somewhat time consuming and error prone. We would have been expulsed for cheating had we used calculators.

@ Stefan:College calc(ulus).

@ myth buster:I thought Mirai Nikki, specifically the Twelfth.

*wipes a single tear off*

I have never seen a more relatable comic page.

@ TvTropesgotmehooked:To be honest i never liked the imaginary numbers… for one there is no point to defining them seperate… they are just real numbers on a different axis. Their only use is as part of the complex numbers.. and i never got why they couldnt use proper vectors for those… its just another R² after all(with a fairly specific definition of multiplication tho) and introducing it as such would be so much cleaner and would probably make learning the R^n spaces a lot easier…

@ Sharien:No, complex numbers are not “just another R²” with a funky multiplication. They are the smallest extension of real numbers that is closed with respect to taking roots, thus making all polynomial equations solvable.

Also, multiplication by a complex number corresponds to a transformation of R² that scales by a real coefficient and rotates by an angle φ about the origin. Multiplication of complex numbers corresponds to composition of such transformations, and it is both associative and commutative. This property is unique to complex numbers.

The next Rⁿ with an interesting multiplication is R⁴, corresponding to scaling and rotations of the R³ space. (See quaternions.) Quaternion multiplication is associative but not commutative.

@ Centaur:Fine they are a useful R²… doesnt make them not a R² vector space

And in terms of learning it is more sensible in my opinion to first teach what a R² is and then introduce the complex Numbers as a special R² with all of its properties of nicely extending R…

But that is just my opinion…

Heh. Glad to see someone else (even if it is a number) likes Pi. Pie. Sorry. And poor Cloud, getting stabbed with a root.

You think that’s hard? Try memorizing all the Laplace transform functions and solving for the inverse Laplace transform of a differential equation. Now that’s hard.

This is freaky like an horror art pic, classic like Picasso, and has a body count like an old samurai movie. I love it.

(I apologize in advance for a childish joke that contrasts so strongly with the deeply mathematical talk above…)

That 1st panel – pi fight!

Ezrawrote:I think you’re thinking too far. It’s like a greater/lesser sign but the unknown could be equal to the number too.

“Aleph-null bottles of beer on the wall,

Aleph-null bottles of beer;

Take one down, and pass it around,

Aleph-null bottles of beer!”

Sandra will rescue Cloud as soon as I finish the song. Fear not.

And the worst part? This is a 30 question test.

Hmmm. Not criticizing the comic, as I doubt that most people would see this the way that I did, but having spent a fair amount of time in Cambodia and having visited Tuol Sleng and Choeung Ek, I wasn’t able to appreciate the humor this time.

@ myth buster:That’s actually what I was thinking.

@ Greenwood Goat:Well if ot is 0÷0 just take the derivatives of the numerator and denominator and if you have c÷0 where c is a constant where c!=0 then it is undefined else wise it can be solved.

@ CSJTFJ:I have a friend from Cambodia and yeah, wasn’t going to say anything but it wasn’t the best choice for a title IMO.

x9comegawrote:Even worse, hexadecimal. So 48 questions!

And this is why I flunked math.

Looks as though #1 is carrying a pair of pi cutters!!
