  1. does this one have a graph like this ?? does the word basis has something to do with the propogation with an interval ??
  2. linear maths ?? ok .. i never thought something which had a linear polynomial would end up so complicated ... in my understanding ... i was classyfying all these to .. linear polynomial ... a polynomial of degree one .. non linear polynomials ... polynomials greater than degree one .. quadratic ... cubic ... and quartic .... ( and being able to solve them through factoring and indetities ) in my mind , the advanced maths meant ... functions .. differentiation ...intergrations ... isnt all this .. related to graphs ??? the linear ... the non linear plolynomials??? the complex numbers ?? the differentiation ?? integration ??? sorry for going off topic too much ... but these are all the things running through my head right now ....
  3. a polynomial with degree one ? isnt that what is called by linear algebra ??? i am only familiar with the degree and coefficients in a polynomial ... no , i am not familiar with the term base ...
  4. i found this book online ... a graduate introduction to numerical methods ... let me see if i can focus on simple polynomials , to try to and solve a few questions .. or atleast try to understand them properly ... in it ... currently i am only familiar with .. polynomials , their degrees and their coefficients ... i have not come across a lot of books like these ones ... let me try to read its simple parts ... and see if it makes any sense to me ... changes of polynomial bases ... ?? i have to understand that change a bit ... i will spend my free time in understanding the polynomials ... so that sometime in the future i can try one or two examples like that mentioned above ..... thanks ...
  5. thanks a lot ... this has to be the best explanation i have ever read so far ... all of this makes a bit more sense right now ... even the books i read were very confusing , so was some websites i went through ... none of them had proper simple examples ... my text book was called computer oriented numerical method ... it had computer programs dealing with polynomial numerical methods ... but it was lacking good example questions ... so i had a very hard time understanding all those.... i have little experience using excel sheet ... i can do table , autosum and little things like that in it .. at this point i dont know if it is capable of doing advanced maths on its tables .... anyway i have to re read everything when i get more free time ... you mean numerical method is useless if the quadratic has complex roots ???
  6. let me start with the very basics itself ... this is therefore a quadratic equation ... i actually took this example from youtube , to make sure ... this problem has a proper solution ... anyway , this is how you usually solve a polynomial .. right ? https://www.youtube.com/watch?v=g7_llQnLepA x = 14 and x= -2 is the answer ... how else would i solve this ?? where would i apply the numerical methods on this one ??
  7. we had that much amount of stuffs to study .. there are many stuffs i dont understand about all those ... i am trying to find the simplest from it to work with examples ... i think ... i have no idea , which one is simplest among those two to look for an example ... does those two only deal with polynomials of degree one ?? even if it is only dealing with polynomials of degree one , how does an example look like .. ?? and what am i trying to solve ? what is this interval they all speak of ... and what increments or dicrements in these problems ? the co eficients ? the degree of the polynomial ?
  8. i have lot of doubts regarding polynomials and numerical method .. can someone help me understand some basics of it ... ? how do i dissassemble this sofa of polynomial properly ? and how does numerical method help ? can i have an example of a simple problem where i can utilize numerical method ???
  9. sweet .. thanks for all the suggestions ... i am a user at library.nu .. ( the site has loads of ebooks ..) so please suggest a nice book if you remember any ... even though i can understand bit of complex numbers .. mostly the basic operation like addition, subtraction, divison ... i dont know what else is there ... but i cant understand any part of "complex geometry"
  10. i have three months to study everything in the "heading " where should i start .. my whole life is depending on this crap .. seriously .. help ...
  11. d/dx sin = cosx d/dx cosx = - sin x d/dx tanx = sec2x then chain rule ... composite two functions and composite three functions ... d/dx f(x)og(x) Df(x)og(x) * Dg(x) ------------------------------------------------------------------------------ d/dx f(x)og(x)oh(x) Df(x)og(x)oh(x) * Dg(x)oh(x) *D h(x)
  12. i have sort of figured out chain rule for two composite functions .. and thank god it works .. sin x xrise 4 xrise 3 so this is three composite functions .. i cant get the answer the way i am working with .. i wish i had more examples to work out, of functions including only "two composite functions" i will deal with three , later ...
  13. derivative (outer function ) (whole terms) * derivative (inner function) ?
  14. need a short break and a bit of revisions .. be right back ..
  15. so you throw this package in the box ?
  16. if differentiation was about finding slopes .. between points .. how many points are we dealing with here ? i think the derivative of sinx is cosx .. sqrt of x = x^1/2 which is 1/2*x^1/2-1 isnt it ? i am writing that down .. and learning it .. very nice tutorial mr cap
  17. dude i was thinking about putting it in a graph .. one by one in a transparent graph .. one top of another .. wtf is this shit then ? this function takes x as input ? if i had one graph that was like .. f(x)= sugar root of sinx which could take x as input ... so f(1) would be like ... f(1)= sugar root of sin1 find dy/dx silly but if you have .. it would be really nice if you could reply
  18. how do i graph one ? with f (1) f(2) f(3) then find the slope ?
  19. which is same as y = ^ i hope .. anyway .. help
  20. ok .. cool was working my ass off ..lol .. and not reaching anywhere ... exhausted to the mathz ... now , since its like a sum .. i should use chain rule ? yes ? could you show me how to ? according to that f(x)= so here y = f(x) .. means that ? the amount of y changes if x changes in a very short extent .. ?
  21. the big square root and derivative .. ok .... step (1) X (into) derivative of two more square root of sinx ? how many terms are we dealing with here .. you know if it was a ploynomial .. there would be two or three terms .. right ? and we usually find the derivative of each term .. yea ?
  22. lets see .. a single y is sinx+sinx+sinx so .. am i trying to find the second y ? first let me clear that .. and will continue ..
