I often find it useful to add some mathematical or greek symbols in my scientific computing Python programs (mainly in commentary). Here is a selection I've taken from Gnome Character Map for math. Greek was mainly generated by a Python script...
Math
| Arithmetic | |
|---|---|
| plus-minus | _ ± |
| multiplication | _ × |
| division | _ ÷ |
| power | _ ² ³ |
| root | _ √ ∛ |
| infinity | _ ∞ |
| Operators | |
|---|---|
| integrals and sum | _ ∫ ∬ ∑ |
| partial diff. | _ ∂ |
| increment/Laplace | _ ∆ (different from Greek delta : Δ) |
| nabla | _ ∇ |
| expectation | _ ⟨⟩ [apparently the double-struck E symbol kills Worpress...] |
Relationships
- equality = ≈ ≠ ≡
- inequality < > ≤ ≥ ⩽ ⩾
- proportional to ∝
- element of ∈ ∉
- subset of ⊂ ⊄
- quantifiers ∀ ∃ ∄
Sets
- integers ℕ ℤ
- real numbers ℝ
- complex numbers ℂ
- empty set ∅
Arrows
- arrows : → ⟶ ⇒
- maps to : ↦ ⟼
Greek
pairs of lower case and upper case letters (putting a dot on letters which have very similar latin counterparts)
α .
β .
γ Γ
δ Δ
ε .
ζ .
η .
θ Θ
. .
κ .
λ Λ
μ .

π Π
ρ .
ς .
σ Σ
τ .
υ .
φ Φ (and also ϕ at U+03d5)
χ .
ψ Ψ
ω Ω
This greek table was first generated by these three lines of Python:
l = [unichr(a)+u' '+unichr(b)
for a,b in zip(range(0x3b1, 0x3ca), range(0x391,0x3aa)) ]
print(u'\n'.join(l))
