If you listened to music, your phone used them about a billion times. … well, not exactly since more efficient algorithms than full perfect computation exist, but…
Same for GPS, cell signal processing, camera functions… They’re all over the place. Taking that picture required it.
Like I said: more efficient algorithms have been figured out. That doesn’t mean those equations are magically meaningless or not involved conceptually. Trigonometry is everywhere, doing important things.

While it is necessary to understand the background, digitized sampling and Fourier transforms of the data don’t calculate sin/cos/tan.
