does cauchy schwartz inequality have any applictions or is it yet another useless formula I have to memorize f or exams?

so yet another useless formula then?

OP asked for applications and I posted one. Get off my dick.

>cauchy schwartz inequality
It is called the Bunyakovsky inequality.

>>5325665
which is to say it has absolutely no real value in day to day life

>>5325682
Nothing has real value in day to day life as we are all going to die anyway.

>>5325665
You can also derive the Heisenberg Uncertainty principle commuting matrices - that's how Heisenberg actually did it.

Also, there's no truly "useless formula". They all have their applications.

this Bunyakovsky fellow seems ultra hardcore

Daww, babby can't handle basic functional analysis?

You're not supposed to memorize anything in maths

Are you retarded? That's babby's first linear algebra.

>> No.5325714

>>5325708
cauchy-schwartz generalisations extend way beyond linear algebra

if you didn't have a redpill moment when cauchy-schwartz was first proved to you, quit while you're ahead and change majors

Is it not one of the main ingredients of the proof that the usual Euclidean distance between points/vectors is a metric?

>> No.5325801

The Cauchy-Schwarz inequality is like the mother of all inequalities...
