Question

What the freaking mittens is polynomial interpolation??

Answer 1

Can mittens be freaking?

Answer 2

I have no idea, so it's probably not that important. It's probably when you like transform it somehow.

Answer 3

Linear Algebra BS

Answer 4

you are trying to find a polynomial give some points

Answer 5

given*

Answer 6

i like freaking mittens

Answer 7

You like freaking what?

Answer 8

Freaking mittens is what I say to sound frustrated.
I have a college exam here guys. I'll have to take remedial math if I don't find out, and the net is being really tedious..
Polynomials are.. variables raised to whole numbers? Right?

Answer 9

yes

Answer 10

I only like the non-freaking kind. But yeah, polynomial interpolation is basically finding the line/polynomial of best fit.

Answer 11

Best fit to what? Honestly, they announced this exam two days back and haven't even defined any of the course except for "interpolation".. i'll just look up the darned
definition of interpolation

Answer 12

What class are you in?

Answer 13

Best fit for a set of data points

Answer 14

I actually teach high school math (geometry and calculus mostly)

Answer 15

Um, I'm 19. Uni freshman.

Answer 16

Then just take remedial math. You've got plenty of time.

Answer 17

Polynomials interpolation can be used to approximate more complicated curves. A relevant application is the evaluation of the natural logarithm and trigonometric functions where you pick a few known data points, create a lookup table, and interpolate between those data points. So it is a way of approximating a more complicated curve using simpler polynomials, often lines. This how they do most of the graphics for video games, or movie CGI.

Answer 18

"polynomial interpolation " sound too advanced for college freshman

Answer 19

i thought my definition was easy :(

Answer 20

By the way, I like the expression freaking mittens!

Answer 21

Oh i see. Finding the equation of a curve using the given points in a given graph.

Answer 22

Haha, I say it a lot.

Answer 23

Is that it? By the way, thank you guys. You're all really helpful!

Answer 24

here is an example
a polynomial has only zeros 4 and 3
so the the polynomial that satisfies the set of points (4,0) and (3,0) is
P(x)=(x-4)(x-3)

Answer 25

or we could say P(x)=a(x-4)(x-3)
to be more general

Answer 26

where a is some real number

Answer 27

I see. I get it now. Doesn't seem hard after all.. it was probably somewhere in my A Levels too. I better buy a textbook related to their course though..

Answer 28

Why do they give them such scary names??

Answer 29

cuz of greeks and latin mathematicians influence ..... however if u ever need any assistance do inform we can setup a tutorial for you btw i did tracked you down as you are not responding on fb my curiousity got really humungous and searched you all over the net ...but the journey went interesting and knew a lot but still not a whole lot ..... u r deeper than an ocean and biblically creative i found u very creative, imaginative, scientific and finally ghostly :) and u r correct ....... sulky as u said and very unique ...........i request u to please reply i have few things to share with you and whatever the case atleast reply. many thks your Mentor!
