A Helix has length. A Spiral has no length. Pitch for a spiral is "Final diameter" - "Start diameter" divided by "Number of turns". (FD-SD)/NOT. WebOct 6, 2024 · This solution is given as follows (here, in the complex plane). The Fermat spiral is given by z = r ( θ) e i θ, where r 2 = a 2 ⋅ θ. The arc length is given by. s = ∫ z ˙ d θ. Thus, z = a θ e i θ z ˙ = a ( 1 2 θ + i θ) e i θ z ˙ = a 1 4 θ + θ s = ∫ z ˙ d θ.
