Wow. You're really stupid of you think its just an algebra problem

>>28387075
This, just becuase you can use it as part of a proof doesn't mean that it in itself is a proof.

>>28387095
You'll understand when you pass geometry, kid.

>>28387092

what were they being asked to prove then? I skipped parts of the movie so I guess I just missed this. The work in this screenshot just looks like a standard "Here is a triangle. There are some lines intersecting its side. Some of the angles are given. Some are left blank. Solve for X where X is some specific angle"

>>28387133
You can Google that triangle. It's apparently a famous problem. I did it and it's EXTREMELY HARD. I read about it and it takes most mathematicians a few days. I went into it thinking "this looks easy, I'll just do some simple adding/subtracting ad find X" but that triangle took me longer than id like to admit. You have to prove a lot of other angles before you can even get close to finding X. That's what all that writing is, is all the proof for the angles.

>>28387133
>>28387158
And you're not allowed to use trigonometry. Only "elementary geometry" which is why it's called the "hardest easy geometry problem"

If you look at Sunny's work, you can also see her mistake, which was a simple arithmetic error. She said 30 + x = 50, x = 30. Simple error. We've all done it before.

>>28386788
Yep, she could have been demonstrating a sine function with a transformation

>>28387158
>>28387198
Thanks anons. This is legitimately interesting. I've never seen this problem before even though I majored in math. If I ever get to teach a Geometry class at a college, I know what I'm assigning as extra credit.

>>28387237
That's hilariously cruel. Have fun

>>28387115
A proof requires a statment that needs to be proven. Much like something isn't an awnser if there wasn't a question.

It's a subtle distinction, but an important one.

Sorry I am allergic to mathemathics
According to neds declassified guide I am a caveman that eats mud.

>>28387292
There was many statements within that problem that had to be proved.

>>28386685
Epic. Look up what a Fourier Transform is and come back with results.

>>28387237
I still don't see the big deal about this problem. It's tedious. That's it. It's like trying to do a problem that would be quick to do with multiplication but you're only allowed addition.

Or common core.

Until like, last year, teachers/schools got punished / lost funding if their students didn't get a certain score on these state-mandated tests. And the score they had to get got higher every year. It was basically impossible to do without cheating, so it led to teachers helping students cheat on tests.

Congress finally did away with almost all of it last year I think.

If most people learn trigonometry in 7th grade, then most people learn calculus in 9th grade.

Who cares, public school is crap!

>>28388095
Naw, that would require too much coordination between middle and high-school curriculums. I learned Trig when I was 13 but could only take calculus in 12, when I was 17.

So your track was:

8th grade: Trigonometry
9th grade: ?
10th grade: ?
11th grade: ?
12th grade: Calculus

>>28388135
Pretty much, yeah. A lot of time in each unit was spent making sure people were on the same page because a lot of teachers were trash. I spent a lot of time re-learning shit then adding one or two new concepts on top of that and then jumping into the next unit.

I'm seriously considering going through my old notes to see just what the fuck we were being taught all those years.

>>28388157
Well that explains it. You and your classmates "learned" trig in 8th but almost none of you actually learned it.

>>28388169
Like I said, it would require the middle and high-school streams to actually communicate.

>>28388078
I learned it in 6th grade

>>28388202
I think the usual track is something like:

8: Algebra II
9: Euclidean Geometry
10: Trigonometry
11: Precalculus
12: Calculus

Cohesive curriculum.

>>28388212
Some people do this, and then learn calculus in 8th grade. I knew a few like that. They then commuted the local university to learn linear algebra in 9th grade, and so on.

>>28388224
I ended up in a lot of advanced classes. And now I'm riding on a GED. Life is strange.

Well in an alternate universe they were in high school, and we don't know what age they switch to their "adult pony graphic".

The only concrete age is that Rarity was already an adult on Sweetie Belle's 5th birthday. Maybe the CMCs are late teens and Rarity is just old.

Good luck teaching kids that. They'll only hate math and science more. Right now, they're hating on why you have to use long pretentious-tier words on essays and not just simple words that you normally use on conversations. You really want to make it worse by making them hate math and sceince by making it hard for them?

Don't get me wrong. I would like it if I had extensive learning in math and science in high school. But I don't blame people who mistakenly hate math and science because the curriculum is too hard for the majority of the students.

If you've watched any cartoons and know basic calculus, you know this is the case with almost all math formulas.
They only need to show something that looks mathic-y and always a step ahead of the kids so they don't question the logic behind it.

You sure about that, bud?

U mad bro?

>>28395199
Let us assume the following:

One carrot + one apple can be the following: swirl * Xl over a Fluttershy hair extension, the derivative of resistance, or barrel to the power of x.

The derivative of resistance + ((swirl)(Xl)/Fluttershy hair extension) = barrel^x

If (one carrot + one apple) is equal to all three of these, then it stands that the derivative of resistance, (swirl)(Xl)/Fluttershy hair extension, and barrel^x all equal 0. Therefore, we can confirm that:

The derivative of resistance = 0
(swirl)(Xl)/Fluttershy hair extension = 0, for all Fluttershy hair extension ∈ R\{0}
barrel^x = 0, which means that barrel = 0

The graph shows one side of the fringe pattern for light shining through a single slit. Local minima can be observed twice, a local maxima can be observed once. No central maximum at x = 0 is visible.

By plugging in values, we can confirm that, assuming m is the integer 1, the wavelength of the light that was shone through the slit was 46.18 apples to the power of barrel^x, divided by the derivative of resistance. In human terms, 681 nanometres, which means red light. Coincidentally, apples are red. Therefore, Cheerilee is presenting a messy proof of why apples are actually red.

>>28399825
I don't understand what you mean. The integral is taken with the starting point at x=pi/2.

>>28399822
It is. I should know because all three of those are my posts. Remember that t is only a dummy variable, as it does not show up outside of the integral. Using x again within the integral for the dummy variable is bad form. Also, I know that it's dumb to assume that they are doing integrals. That's why I said "That's my story and I'm sticking to it". You know, like Applejack did in Party of One when she was making up a dumb excuse.

Anooooooooon, come oooon, I know you can do this. I believe in you!

Find me a credible source that says to do integrals that way, and then we can talk.

So you've just learned about radians? Good for you, now stop using them in every problem like a hammer with a screw

Make it simple.
>>28402735 and >>28402572 shows why >>28395270 doesn't show graph in >>28386641

>>28402882
This is just what >>28402572 shows
Literally a fucking definition (or equation resulting from definition I don't fucking care) you have few lines above.

>Literally a fucking definition (or equation resulting from definition I don't fucking care) you have few lines above.
What's wrong with a definition? You use it to solve the integral, as shown in >>28402504.

>>28403026
I wouldn't call that simpler. That just skips a bunch of steps. At least your result is correct, though.
