Cauchy-Bunyakovsky-Schwarz Inequality II (visual proof)

This is a short, animated visual proof of the two-dimensional Cauchy-Schwarz inequality (sometimes called Cauchy-Bunyakovsky-Schwarz inequality) using "Garfield's trapezoid" and scaling of right triangles.

Amazing job. Fantastic. Keep up the great work.

[@MathVisualProofs]

Thanks!

[@asparkdeity8717]

First! Looks like nobody else is here yet. Thanks for another great video, I have never come across the 2-variable version of this 👍
I also have a video idea - showing that
sin(54) = φ/2, where φ is the golden ratio

[@MathVisualProofs]

Thanks! Yes sin(18) is on my list and so maybe linking that with sin(54) is a good idea.

Please make a vedio upon the division of two irrational number because it is not making any visual image of division under my consideration

Make video on Vector space

This only works in flat space, right?

[@asparkdeity8717]

Sorry what do u mean by flat space?

[@quay6292]

@@asparkdeity8717 Euclidean. Triangle equality always works in space with constant curvature, but not necessarily in space with varied curvature.

[@user-ei6rd7ei7x]

It works in Hilbert spaces.

[@asparkdeity8717]

I would assume so, unfortunately geometry was one of the courses I didn’t take so I can’t answer the question - this inequality is only associated with the Euclidean Norm, so I imagine it wouldn’t work with hyperbolic surfaces

[@rafiihsanalfathin9479]

@@quay6292i think it works for other space but don’t quote me on that

[@kingeddiam2543]

Are there practical applications of this or is it just pure maths?

[@asparkdeity8717]

Cauchy Schwarz (in 3 dimensions mainly) comes up all the time in all fields such as quantum mechanics, it is extremely useful in applied maths

[@kingeddiam2543]

@@asparkdeity8717 cool thank you very much!

[@rafiihsanalfathin9479]

Cauchy scwarz ineq is so useful, it is a basic ineq so there is many applications, not only it is basic but it also practical because it works for all real numbers

[@KinuTheDragon]

The |a||b| for each triangle's sides could have been written as |ab|. Other than that, great video!

[@MathVisualProofs]

Yes for sure! I also probably should have started with just the a,b triangle and scaled that twice...
