@matharium.official: Five waves written as math. A pen traces each function and its height sets the pitch, so you hear the shape: three sines squeezed flat by tanh, a sine riding a four-step staircase, an arctan S-curve with a tremolo, a chirp, and one tone whose volume steps up every 4 units. The chirp is y = 2.9 sin(0.5x + 0.06x3). Its frequency is the derivative of what's inside, 0.5 + 0.18x, so the waves crowd together at both ends and slow almost to a stop in the middle. The last one, sin(2п•3x) (0.3 + 0.24(1x/4 x/4] mod 4)), keeps the same note and only changes how loud it is. Sound on. Follow @matharium for more. #math #music #function #musica #fyp
