1. Last geometry challenge (very difficult)

nah Nah.. I think the answer is R/sqrt2...because you have x^2 = (R/2)^2 +(R/2)^2 and that is simply x^2 =(2R^2/4) and then x^2=R^2/2....so x=R/sqrt2 :)

I've hot two assignments to do in pascal and i have no idea how to make it :( i dont even have anything similar and i dont have time to search the web for answers now I really need help and i need it as fast as it can be so please if anyone can help me with this i would really reallllyyy...
3. Fourier series

hm Not really :frown: the task...as so on my exam..they strictly want it with fourier ... bcs we do also taylor..and in task they mention which one they want..
4. Fourier series

aha Yes i just got it.. it is when you use integr. in series so then it would be ((-1)^n +1) thanx :smile:
5. Fourier series

Well hmm...not really :rolleyes: I did get almoust correct answer BUT... you see b_n is zero but a_n is not...and this is where i stuck ...i cant get correct a_n by the way...can you tell me is this true? cos(npi) + cos(0pi) = (-1)^(n+1) thanx again :smile:
6. Fourier series

Hi there!! Can anyone please help me with this one..? Find the Fourier Sine series of f(x)=sin(x/2) for interval (0,pi) thanx a lot :)
