Hi,
So this is part of an assignment for my numerical analysis class.
The integral is this:
\int_0^{\infty} e^{-x} \cos^2 (x^2) dx
We are instructed to evaluate the integral from 0 to some large A using numerical methods (which I'm fine with), and then estimate the tail, ie...
Why can I only edit my last post? Can I change the thread name etc?
Can I delete the post to rid this forum of a useless post?
I looked for this info but couldn't find it.
Ok there was a working error. My bad.
It turns out it is the same.
I learned latex tho so that's good.
I'm trying to work out how to delete this or mark it as DONT READ or something now.
Thanks for replying.
Ok so here is the working for the first, incorrect part.
f(x) \sim \sum^{\infty}_{n = -\infty} C_n e^{-inx}, \ where \ C_n = \frac{1}{2 \pi} \int^{\pi}_{-\pi} x^2 e^{inx} dx \\
Proceeding to calculate Cn using integration by parts
C_n = \frac{1}{2 \pi} \{...
Hello,
First post. I will attempt to use latex, something that involves me jabbing my keyboard with a pen since my \ key is missing.
We have an assignment question which I have solved, but there is a deeper issue I don't understand.
We are asked to find the complex Fourier series...
