Estimating the integral of a decreasing trigonometric function
Yeah I just realized that my way is retarded and ends up with the exact same result. Thanks!- TehAdzMan

Estimating the integral of a decreasing trigonometric function
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...- TehAdzMan

Graduate Complex Fourier Series: Uncovering the Mystery of Different Results for x^2
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.- TehAdzMan

Graduate Complex Fourier Series: Uncovering the Mystery of Different Results for x^2
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.- TehAdzMan

Graduate Complex Fourier Series: Uncovering the Mystery of Different Results for x^2
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} \{...- TehAdzMan

Graduate Complex Fourier Series: Uncovering the Mystery of Different Results for x^2
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...- TehAdzMan
