if you don't want to help then why are you replying in my thread. but seriously i can't find what I am looking for i know about this google thing and i have tried that before making this thread. i know there is a lot of information about fourer series and some transform. but I've noticed...

can you please link me to some. the only video i know of is the standford lecture Fourier transformation and its applications. but its not what I am looking for. he doesn't go through examples and solving problems. (as i have seen maybe I am wrong?). so please link to where they explain time...

I was going to post this in the learning material section but i didnt have access to it for some reason. but i guess i can post it here. its homework after all. so i have noticed that there is almost nothing learning material on fourer transform on the web. like how to transform a function to...

hey i think the limit is 1 1/(n+1) → 0 and 1/n → 0 if both powers will go → 0 then everything0 = 1 then you get 1/1 = 1

Homework Statement i need to solve this diff equation. y' = x2 + y2 y = 1 when x = 0 i can assume that the answer is a power series on the form Ʃanxn andi only need the 4 first non zero terms of the power-series answer Homework Equations Ʃanxn The Attempt at a Solution...

i think that's not right at all and its not funny to trial and error matrix calculations.. they are pretty intense and tiresome can you please give me some more hints.. if you know how to do this. because i have no clue anymore. EDIT: alright it worked..a little miss calculation. thanks...

do u mean the matrix should be [(1,1),(1,(1/2)),(1,(1/3)),(1,(1/4)),(1,(1/5)),(1,(1/6))]

Homework Statement number of years(x): [1,2,3,4,5,6,] number of accidents(y): [12,6,5,4,2,2] or (1,12),(2,6),(3,5),(4,4),(5,2),(6,2) Homework Equations the relation between x and y is on the form: y = a + b(1/x) by changing (1/x) to z, the model become linear instead of...
