does square root have any applications in real life?

>> No.9803747

Ancient Greeks didn't know square roots and after they came into certain point in maths, they couldn't go any further

>> No.9803752

Yes. A thread died for this?

>> No.9803772

what are these

no applications though

>> No.9803779

Concept of having number "zero" also doesn't have any application in life (you don't need anything to represent nothing), but it was crucial for science to have a zero

>> No.9803794

so it's crucial for purely theoritical science and doesn't have any applications
I knew it

>> No.9803811

You have a square wheat field of 500,000 square meters. How long is each side of the field?
You fall out of an airplane at 20,000 feet above the surface of the Earth. Neglecting air resistance, how fast will you be traveling when you hit the ground? Alternatively, once you clear the plane, how many seconds do you have to live?

See! Important practical questions. As the ground gets closer you'll realize how foolish you were to neglect studying math.

>> No.9803818

Generally speaking, math as basic as the square root is mostly useful as a foundation for the really useful stuff

That and distances. Square roots are integral to finding distances when you can't directly measure them

>> No.9803821

What do you mean by "real life"?
I'm sure some people have a life that requires utilizing square roots while others do not.

>> No.9803823

square roots define length in euclidean space and there so many countless formulae that involve them. you can delete this thread now, OP.

pythagoras theorem

What the actual fuck does this thread has to do in here? GTFO OP and learn some elementary school math.

>> No.9803846

>Does *elementary operation* have any application in real life

Brainlets like OP with a mental horizon of radius zero are the reason why textbooks are loaded with contrived word problems designed to make you feel like you're not actually doing mathematics.

>> No.9803858

Square root of 69 is 8 something right? Cuz I been tryna work it out.

>any applications in real life
In the real life of smart students, yes.
In yours, no.

>> No.9805248

even dumb people use square roots

>> No.9805260

yes because when i'm falling out of an airplane i would be solving a quadratic equation

When you get out of highschool and go into construction you will use it quite a bit. Well, your manager will at least

>> No.9805305

apparently not, see

>> No.9805368

0 allows decimals and multiples of 10. Both are important for even the most basic money stuff

>> No.9805382

Well, if you neglect air resistance your body is approximately following the path of a parabola as you fall out of the plane.

>> No.9805403

Only if your notation is positional. Location numerals and their recipricals can describe every real number except 0

>> No.9805519

None what so ever. Don't let degenerate mathophiles tell you otherwise.

Not needed. It is an industry myth to keep the manager in a higher pay bracket.

>> No.9805557

and if we dont neglect air resistance

>> No.9806170

you need square root to find the speed of light. after you divided the energy by the mass.

>> No.9806271

How /sci/ has fallen...

>> No.9806294

No. 0 makes multiplying/dividing by 10 easier and more practical, but having zero is not crucial to make this operation. In Romanic notation, X*X=C, and X/X=I, everything works here

>> No.9806400

his manager won't

I used >>9803826 in Minecraft to find the right number of blocks diagonally to create the same distance as a certain number of blocks in a straight direction.
