How to insert math formulas in this forum

To post math formulas in this forum, you can use the following method:

1/ Insert your TeX code in this LaTeX renderer and create an image of the formula.

2/ Either host the image and include it in your post, or write directly the LaTeX code in your post (allow for some hours before it appears).


Example:
LaTeX code:
\bf
\int H(x,x')\psi(x')dx' = -\frac{\hbar^2}{2m}\frac{d^2}{dx^2}
\psi(x)+V(x)\psi(x)

You can also use utf-8 characters:

‰ ± ≃ ≅ ≈ ≠ ≡ ≢ ≤ ≥ ħ ƒ ℂ ℍ ℕ ℙ ℚ ℝ ℤ ℑ ℜ ℘ ℵ ∞ ∀ ∃ ∅ ∈ ∉ ∋ ∌ ∖ ∏ ∐ ¬ ∧ ∨ ⊻ ∩ ∪ ⊂ ⊃ ∂ Δ ∑ √ ∫ ∬ ∭ ⊗ ′ ″ ‴ ∠ ∢ ∥ ∦ Γ Δ Θ Λ Ξ Π Σ Φ Χ Ψ Ω α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ ς σ τ υ φ χ ψ ω ‣ ← ↑ → ↓

To insert super/subscripts, use the sup, sub tags:

Code:

x[sup]i+1[/sup]

xⁱ⁺¹

Code:

x[sub]i-1[/sub]

x_i-1
