Whispers of the Abyss

Let x = the echo

∫ (y² - 1) dy + ∇ (depth) = 0

Where y is the unspoken fear

f(t) = { sin²(t) | t ∈ [0, ∞) }

Beyond the waves, a spectral light

g(x) = exp(-αx) + βreal

Navigate through the shadows, find the equations that bind the wave and the whisper:
time is an illusion, reality a complex derivative.
