<p>“Forget about fourier analysis, I’ve never seen it once at work… used to be able to do it at one point, but totally forgot now…”</p>
<p>Really?? I use it every day. It depends on the field you are working in. The math skills that are required are not consistent across fields.</p>
<p>Fourier transforms are easy. You should be very concerned if you find them difficult and they are a lot more straightforward than abstract math.</p>
