Supported Functions

Trig: sin(), cos(), tan() in degrees or radians. Logs: log() base-10, ln() natural. Powers: ^ for exponents, sqrt() for roots. Constants: pi, e. Other: abs() for absolute value, parentheses for grouping. Type expressions naturally like a formula.

Examples

sin(30) = 0.5 · log(1000) = 3 · 2^10 = 1024 · sqrt(3^2 + 4^2) = 5 · pi * 5^2 = 78.54 (area of circle r=5)
