Yes, but what about the *cones*?

2. offensive_james says:

Maybe I’m not a smart man, and so maybe I’m not getting this, but what is this educating me with?

You tear a chunk out of a cone, slap it on its side and what?

Is this video showing me the relationship between a cone and shapes? Or specially what shapes mean what (and the cone is incidental)?

I’m sure these have obvious answers when you’re already mathematically minded, but pretty shapes aside, i have no idea what I’m looking at

3. Ostrololo says:

Well, there are actually *two* cones. Without the second one, it’s not immediately obvious what the difference between the parabola and the hyperbola is.

4. AssKicker1337 says:

If you slice it straight down the middle, do you get a triangle? And if so, why do we not consider a triangle as a conic section?

And the last one on the mid?

7. raybrignsx says:

How dare they skip parabol and go right to parabola.

Isnt that “hyperbola” just a steeper parabola?

10. slaps-first says:

I thought it would be the ICONIC shapes

11. Yes_Everytime says:

What a trash post, I did not see a plane crash into that cone to “slice” it. Probably would have been better using a helicopter.

12. ShiftTM says:

It must’ve been a very small plane, I’d be surprised if it could even fly

13. Serafim91 says:

This was by far my worst math class in college. Honors level freshman course with a prof that sucked, don’t remember anything at all from it except the integrals get nasty.

Don’t show this to Ben or he’ll have to redo the Cones of Dunshire and find a way to implement this new conical technology.

16. IcanSew831 says:

I’m curious what the big odd shaped lump in the middle is called.

17. [deleted] says:

This is truly not impressive.

I want this in my house !

19. symbologythere says:

All I remember about an ENTIRE year of high school math was the math teacher’s running joke….”What’s a parabola?……2 bola.”

20. DMvsPC says:

One of my students made a 3D printed model of this using the equations for the curves, I probably have the stl file somewhere.

21. carchit says:

I’m still traumatized from having to hand draw those shapes generated by a sliced cone. Descriptive geometry was taught in architecture school in the pre digital era.

22. SassHole1756 says:

This is cool.

23. ibraheemMmoosa says:

Why were they interested in slicing cones?

24. IRonyk says:

Isn’t the last one actually the parabola…
And the 3rd one the hyperbola

Edit :yup they are right

25. yee2446 says:

Ok.

are there squaric sections?
