> As an electrical engineer you'll typical use f, ω, and s, in different contexts and you'll learn each of those contexts separately. Perhaps it's just my unconventional education (see username), but when I'm doing something like filter design, I really do end up using all of those at once. I'll do the on-paper design portions with s, the computational section of the design with ω, and then when I build the thing to test it, the scope or spectrum analyzer read out in f (if I'm lucky). So they're genuinely all there at once!
