MathQuill fields support a LaTeX-like syntax that is converted into JavaScript expressions for evaluation. Here’s what works:

Supported (LaTeX → JS)

• Trig: \sin, \cos, \tan
• Logs: \ln, \log → Math.log
• Roots: \sqrt{...}, \sqrt(...), \sqrt x → Math.sqrt(...)
• Exponential: e^{...}, \exp{...} → Math.exp(...)
• Reciprocal trig: \sec(...), \csc(...), \cot(...) → 1/Math.cos|sin|tan(...)
• Absolute value: |...| or \left|...\right| → Math.abs(...)
• Constants: \pi → Math.PI, bare e → Math.E
• Operators: ^ or ^{...} → **, \frac{a}{b} → (a)/(b), \cdot/\times → *

Displayed (JS → LaTeX)

• Math.sin, Math.cos, Math.tan
• Math.log → \ln
• Math.sqrt(...) → \sqrt{...}
• Math.exp(...) → e^{...}
• Math.abs(...) → \left|...\right|
• Math.floor, Math.ceil → \lfloor \cdot \rfloor, \lceil \cdot \rceil
• Constants: Math.PI → \pi, Math.E → e
• Operators: ** → ^, * → \cdot

Limitations

• Not parsed: \asin/\acos/\atan, hyperbolic and inverse hyperbolic functions, \lfloor/\lceil (as LaTeX input), \max/\min, piecewise.
• Nested/complex \frac and deeply nested expressions may not convert perfectly.
• Implicit multiplication is conservative to avoid breaking function calls; insert * if something doesn’t evaluate.
• Always click the scene’s Apply/Update button to re-run with your changes.

If an expression fails to apply, share the exact input to me so I can try to extend support for it.
