Zeta (ζ ), Phi (ϕ), Delta (δ), and Aleph (א) are characters seen in Animation vs. Math.

Appearance

Zeta, Phi, and Delta have an appearance of a small version of their respective letters in Mathematical Sans Serif font. They are on scale with Euler's identity, with Zeta being the tallest and Delta being the shortest.

Aleph on the other hand, is represented by a piece of the complex plane that forms the symbol of the same name in Mathematical Sans Serif. The top and bottom of it becomes much more opaque. Aleph is very large compared to the other symbols, as it represents an infinite set rather than a constant.

Role

Animation vs. Math

They come at the end of the episode to comfort and possibly befriend Euler's identity and walk/bounce away.

Trivia

• Each of them are a character of mathematical functions (excluding Aleph, which is a set consisting of infinite numbers) that has a relationship with Euler's Identity or with infinity.
• Zeta, Phi, and Delta are letters in the Hellenic Script, while Aleph is a letter in the Hebrew Script.
• Phi appears to make a metallic sound while walking, confirming in this case, Phi equals the Golden Ratio which is approximately 1.618033... and so on. [1]
• Zeta, as represented here, should be the Riemann-zeta function: $\zeta (s)=\sum _{k=1}^{\infty }{\frac {1}{k^{s}}}$, an important and common function used in complex analogy.
