Trigonometry & Angle Units (DEG vs RAD)
Trigonometric functions like sin, cos, and tan evaluate angles in either Degrees (0° to 360°) or Radians (0 to 2π). Toggle DEG mode for standard geometric calculations and RAD mode for calculus, physics, and wave analysis. Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) convert ratios back to angles.
