Unless you're going into the STEM business, there's no reason to need to know the volume of any solid other than some simple elementary shapes like spheres or prisms.
In those cases, a simple intuitive formula is enough and it makes sense to most children.
Why would you want to teach children calculus before they're even able to do simple algebra?

Well, volume of figures using definite integrals just isn't something you can teach very quickly. There are way too many special cases and methods. Disc about x axis, washer about x axis, disc about y axis, washer about y axis, disc and washer about horizontal axis besides x axis, disc and washer about vertical axis besides x axis, shell method and why you'd use it/when it makes more sense, examples where you could use disc/washer OR shell method and understanding how to do both. And many more exceptions and applications. It's a lot, if your high school Calc course is good.

In the 50's formal set theory was taught in elementary before basic arithmetic. This created one of the greatest generations of mathematicians ever to exist; in the 60's, freshman maths was comparable to what's now post-grad level math.
FUCK YOU KURISU! A FEW MORE MONTHS IN GRAD SCHOOL AND I WILL SOLVE ALL YOUR SHITTY PROBLEMS, I SWEAR TO GOD.
A section going perpendicular to the basal circle and through the tip shows that it's a right-angled triangle, with basal radius r and height h. Define r(x) as the radius of the cone at height x going from the tip and consider that the slope of the cone is constant, which means r(x) is linear with boundary values of r(0)=0 and r(h) = r. From this follows that r(x) = x / tan(alpha) = x * r/h with alpha being the the angle of the cone mantle. Now integrate pi * r(x)^2 from x=0 to h, which leads to 1/3 * pi * r^2 * h. Insert values at your own discretion.

They will be imprisoned separately. Each day the alien will take 1 random person into a same room, where there are only 2 lamps in it, RED LAMP AND BLUE LAMP, with 2 switchs, which can only be used to turn on and turn off those lamps.
This will last forever, until any of those 50 person say "ALL 50 OF US HAVE ALL BEEN IN THIS ROOM". If he/she tells the truth, they will be free. If it's not true, they will die.
Those people have 10 minutes last meeting to discuss the strategy. Which is the best thing they can do?

The previous episode was more of a tearjerker.

You can learn if you want

Enjoy your shit degree

FUCK YOU
>implying math majors are part of the STE elitist triumvirate
Enjoy your no jobs faggot, I'm doing CS and taking advantage if the current bubble
>>139233702
Enjoy your no job, Indian programmers always do better with lower salary.

This was the most action-packed episode!
>>139232792
Let F be the intersection of AE and BD.
AFB = 180- 60 -70 = 50
Therefore
BFE = 180 - 50 = 130
BEF = 180 - 20 - 130 = 30
Likewise
AFD = 130
ADF = 40
Let s = FED, x = CED & y = CDE, z = FDE
System:
s + z + 50 = 180
x + y + 20 = 180
s + x + 30 = 180
z + y + 40 = 180
Or
[1,0,0,1] [s] [130]
[0,1,1,0] . [x] [160]
[1,1,0,0] [y] = [150]
[0,0,1,1] [z] [140]
Simplifed as M.X= [130,160,150,140] (cauchy problem)
det(M) = 0. There are either no or an infinity of solution.
Resolving the system gives has one of the four equation simplifies itself in 0 = 0, so we need to declare a parameter (let s = t) which simplifies it into
s = t
z = 130 - t
x = 150 - t
y = 160 - x = 10 + t
For exemple t = 10 is a solution for whom all four angles are positive.

I think it's because she hasthe knowledge of almost anythingbecause she's acompleted holy grail
>>139237115
>Let s = FED, x = CED & y = CDE, z = FDE
You need something like s+x+y+z+EFD+ECD=360 to reduce the number of solutions.

Full on schizo.

That formula was found by using integrals FYI
You should be able to solve this.
>>139238102
>That formula was found by using integrals FYI
It actually wasn't.
We knew the formula for the volume of a cone long before the advent of calculus.
>>139238117
That's retarded
z = 1
y = 1
x = 1
>>139224212
1/2 volume of the cylinder
>>139237849
You realize that if
s + z + 50 = 180
x + y + 20 = 180
s + x + 30 = 180
z + y + 40 = 180
is noted
(1)
(2)
(3)
(4),
s+x+y+z+EFD+ECD=360 is (1) + (2), right?
>>139224212

It's π.

Its just Japan don't worry about it, white piggu won't understand.

That's *a* solution. Can you prove uniqueness?

You're right!

z = -1
y = -1
x = -1
>>139238266
Oh I see, your system is underspecified not because of number of angles but because it doesn't exclude angles outside (0,180)
>>139238117
2(xy + xz + yz) = (x + y + z)^2 - (x^2 + y^2 + y^2) = 6
xy + xz + yz = 3
3xyz = (x^3+y^3+z^3) + 3(x+y+z)(xy+xz+yz) - (x+y+z)^3 = 3
xyz = 1
So x,y,z are the solutions of the cubic:
0 = (t - x)(t - y)(t - z) = t^3 - 3 t^2 + 3 t - 1 = (t - 1)^3
This implies x=y=z=1 is the only solution.
>>139238117
>>139230867
Because it's easier?
You don't need to memorize a retarded formula and plug and chug for this.
>>139238440
The Greeks did it first, though, and they used integration to do it.
>>139226392
Same with history classes focusing on memorization of dates and shit like that.
