Hi,
I'm an electrical engineer for a few years now, but it's been a while since I had to deal with this kind of stuff, I turned out to become mostly a programmer in the end, but i was thinking: is Gibbs phenomenon, which was demonstrated to me during my studies while working on Fourier series...
The 1.5 is the average value of the interval from "my" 1 to 2, I wrote that to demonstrate how to calculate the average of the function value to a friend.
You tell me to not forget the interval between 2 and 4, but they do not matter, because they will integrate to zero, this is how I see it. I...
Homework Statement
Given the following periodic signal:
What is the Fourier coefficient b1.
I'm not asking for help with the Fourier series. I feel my integration is solid.
What I need help with is creating the correct function!
The Attempt at a Solution
I first declare t=5 as now to be...
My God, that seemed to do the trick.
This seems right to me.
I gather since I converted from atm to Pa, and integrated using m3 instead of liters, I also should have taken that into account for the gradient.
Is that assessment correct?
Homework Statement
Which of the following combinations (in water) causes a reaction? Write a balanced reaction equation for the cases that cause reaction:
CU2+ + H2(g)
Fe2+ + AG
Fe3+ + Sn2+
etc...
Homework Equations
Not applicable.

Thank you for your help. Gonna ask the professor about it, he made the task after all.
The second term is -(3*2) because that is the gradient of the curve. That should be correct.
Oh, I should have stated that. I extended the IF line to where it intersects with the Y-axis, which is 7 atm.
7 * 101325 Pa = 709275 Pa.
You got 306 J... it should be 505, unless the document is wrong.
Homework Statement
Calculate the gas' mechanical work on its environment for the thermodynamic process path IF.
Solution says: 505 J
Homework Equations
W=\int_i^f p,dv
i = Vi, initial volume
f = Vf, final volume

My approach is to find a...
Thank you for helping me with this!
I think perhaps an error has snuck into your maths though, because you write:
a_{0}=\frac{1}{2p}...=\frac{1}{2\pi}...
But p=2∏, so it should be a_{0}=\frac{1}{4\pi} using your formula.
Can you comment on this?
I understand how there are different formulas...
I think I figured it out... my a0 seems correct to be ∏/2,
but when I type out the actual Fourier series, the formula is:
a0/2, making it ∏/4.
If anybody wants to confirm my thinking, that would be helpful!
Homework Statement
Find the Fourier series representation of:
f(t)={-t , -∏<t<0
f(t)={0 , 0<t<∏
This is a piecewise function.
T=2∏ (the period)
Homework Equations
a_{0}=\frac{2}{T}*\int_0^T f(t),dt
The Attempt at a Solution
I need help only with calculating the DC...
Bingo. That's what I thought, but since the task specified parallel I tried to come up with something.
The problem with the current graph being flat is still there, would love for some Multisim advice on this!
Thanks for the help thus far!
