MerlinoMaths on Instagram: "🔍 The Riemann zeta function in 3D In earlier posts we saw it in 2D, on the complex plane, as a spiral built step by step. Each term was a vector that rotated and shrank, producing fascinating patterns. 👉 In this reel we take it further: we plot the zeta in three dimensions, separating the real part (blue) and the imaginary part (yellow). This lets us see how both components accumulate in different ways. Each term of the series is like a little “step”: one factor mak
