So guys, I'm still lost, for the second part tho I found the answer,, I just have to do a full Fourier series of |sinx|, but for the first time I'm still confused if I should use the half range form or the regular form, and if I have o use the half range, how do I apply it to a function in the...

Let me try this, I will update with my results, thank you! Also the range was already from 0 to Pi/Omega!

This is a picture of my work, but if you can't read it I got $$a_{0} = \frac{4 \omega A}{\pi }$$ $$a_{n} = 0 $$ $$b_{n} = 4n^{2} \int \sin(\omega t)\sin(2nt\omega ) $$ And then that integral keeps repeating :/ (any tips on how to deal with partial integrals that repeat like btw?) thank you!

Hello! So I'm stuck in yet another problem, I've been going through some Fourier Series problems (including one that I already asked about around here, and go great help!) and I've managed to get past most, but I got once again stuck on one. So for this one we got an alternating current of the...

I think that 2 on top of the Pi was there because he had changed the range of the integral, so if we put it back to the original range the 2 shouldn't be there...I might be wrong tho And thanks! I'm new with latex and I was kinda learning as I was going along, I appreciate the tips!

So do you you mean like this? $$B_{n} = \frac{1}{\pi }\int_{-\pi }^{\pi} Cosh(ax)sin(nx)$$

Woah! Thank you! I don't know what to say, you guys have helped me so much! I changed the title of the thread so it shows that it's solved (that's the right thing to do right?) I don't know how to thank you, you guys are awesome! (Bow) I had not realized Cosh(ax)sin(kx) was odd, that helped a lot!

Thank you very much, let me try to finish this, and I'll let you guys know how it goes! (Dance)

So for the first coefficient I got this $$a_{0} = \frac{e^{a\pi } - e^{-a\pi }}{\pi a}$$ but for the second one I keep looping while trying to do integration by parts (I keep getting back to the same integral over and over) Any clue on how to deal with this: $$a_{n} =\frac{1}{\pi } \int...

Ahh! Thank you, I had thought of using this, but I didn't know if it worked when x was next to some constant. Do you think it would be better to first integrate to obtain 1/a Sinh(ax)? I feel like replacing first will make it harder to find some of the coefficients. Anyways I'll try it out and...

[SOLVED] Fourier Series Involving Hyperbolic Functions Hello everyone! Sorry if this isn't the appropriate board, but I couldn't think of which board would be more appropriate. I was running through some problems I have to do as practice for a test and I got stuck on one I'm 99% sure they'll...
