Obsidian supports LaTeX, but there are cases where Unicode symbols suffice.
Run command LaTeX to Unicode. In the pop-up box, type in the LaTeX commands, then insert the conversion results.
Input: 3^2 + 4^2 = 5^2
Output: 3² + 4² = 5²
Input: (x+y)^2 = x^2 + 2xy + y^2
Output: (x+y)² = x² + 2xy + y²
Input: H_2 + \sfrac{1}{2}O_2 \to H_2O
Output: H₂ + ½O₂ → H₂O
Input: -\mathbf{r} \times i\hbar\nabla
Output: −𝐫 × iℏ∇
Input: \sqrt(2) = 1.4142\cdots
Output: √(2) = 1.4142⋯
Input: x \in y \Rightarrow y \ni x
Output: x ∈ y ⇒ y ∋ x
Input: \mathbb{N} \equiv {1, 2, 3, \ldots}
