This just clicked for me. He doesn't like to "spoil the surprise" by giving away the whole idea of a concept (forces us to choose whether to use something he taught or not), so it wasn't directly implied.
The whole idea behind Laplace/Fourier Transforms is to take a differential equation...
It's a math methods course, but we are studying differential equations now. Finished partial diff. eq. on Thursday.
As far as the solution, this is what we did. I was trying to understand exactly what was going on, but then it clicked and I finished it in about half an hour. The answer...
Back again with another problem. These transforms are difficult...

The Attempt at a Solution
His instructions are to take the Laplace Transform of each of Kirchhoff's laws. However, when we do, nothing useful comes...
Using what you said (which makes sense; can't believe I didn't see that), I got this:

There were absolute values, however, I omitted them because I didn't think they were necessary.
I haven't had differential equations yet, so I am struggling in your math methods class. I understand what a Fourier Transform is, but I'm having trouble with this particular problem.
Homework Statement
Here's a screenshot. Better than I can write it.

So, why doesn't the 2 tag along with the rest of the terms? In this case, it seems like there is a piecewise function under conditions n=0 and n>0.
Sorry if I'm asking a dumb question.
I wasn't really sure where to post this because I am covering this in 2 classes (Math and Physics). Figured this would be my best bet.
The Fourier series of some Function is a_{0}/2+etc.... I've looked in several textbooks but none explain why the 1/2 is there, and not in any of the other...
We learned the GSP yesterday in class, but my teacher said something that seems to conflict with the textbook.
He said that we can set our first vector (w_{1}) equal to any vector in the set. However, I keep getting different answers than our textboook when I do this.
My question: Is it...
I was originally going to do that (and basically ended up doing that anyways), but he told me I should use complex-exponentials instead.
What I ended up with was:
u(x)=A \times Cos[(\frac{n \pi}{L}) x]
I wish I had followed my gut instinct instead...Thanks for the help. I don't see a...
First off, I've never taken a differential equations class. This is for my Math Methods for Physicists class, and we are on the topic of DE. Unfortunately, we didn't cover this much, so most of what I am about to show you comes from the professor giving me tips and my own common sense. I'd...
Which is why I am expressing my concern. If I don't, then I lose the ability to fight later if I don't get an "A" in the class, or if I don't have the foundation required by my later courses. If this was a standard business, there would be a lawsuit for services not fulfilled.
I know that...
Then it is a broken system that needs repair. That's where students like myself try to come in and fix the problem.
I taught myself through high school (taking 5 years to do it). I know how to teach myself and I understand the value of education. I'm paying someone else to teach myself...
Sorry if I'm replying to much. I get push updates to my phone on posts, and trying to quote everyone at once is a challenge.
I agree that the student has the majority of the responsibility, but when a student exhausts all available options to learn, and still cannot understand the material...
I don't want him fired. But at the same time, he shouldn't be teaching on a sub-par level. That's what my situation is.
I LOVE my 2500k. Folds like a champ at 4.5GHz. Going to shoot for 5GHz when I get a XSPC Rasa kit.
