1. Mathematical Functions Reference Manual
A. Trigonometric Functions (sin, cos, tan)
Calculates trigonometric ratios based on either Degrees (0° to 360°) or Radians (0 to 2π).
sin(30°) = 0.5 • cos(60°) = 0.5 • tan(45°) = 1.0Conversion formula: Radians = Degrees × (π / 180)

2. PEMDAS / BODMAS Order of Operations
The CalcSolver evaluation engine strictly follows operator precedence:
- P / B: Parentheses / Brackets evaluated first from the innermost set outward.
- E / O: Exponents, roots (√x), and powers (x², x³).
- MD / DM: Multiplication and Division (evaluated left-to-right).
- AS: Addition and Subtraction (evaluated left-to-right).
