  Example (DEG mode):

  sin(30°) = 0.5000000000

  cos(45°) ≈ 0.7071067812

  tan(60°) ≈ 1.7320508076

  Pass Criteria: Results align with mathematical constants (e.g., π, √2) to at least 8 decimal places.
• Logarithmic and Exponential Operations
  Test: Compute natural logarithms (ln) and base-10 logs (log) for values like 10, 100, and 0.1, then exponentiate results to verify reversibility.
  Example:

  log₁₀(100) = 2 → 10² = 100

  ln(1) = 0 → e⁰ = 1

  Pass Criteria: Round-trip operations (e.g., log → exponentiation) return the original input without floating-point errors.
• Statistical Calculations
  Test: Input a dataset (e.g., [1, 2, 3, 4, 5]) and compute mean, median, standard deviation, and regression lines. Compare with manual calculations or statistical software (e.g., R).
  Example:

  Mean = (1+2+3+4+5)/5 = 3

  Standard Deviation ≈ 1.414213562

  Pass Criteria: Results match published formulas (e.g., Bessel’s correction for sample standard deviation).
• Complex Number Operations
  Test: Perform addition, multiplication, and magnitude calculations with complex numbers (e.g., (3+4i) + (1−2i) = 4+2i).
  Example:

  (3+4i) × (1−2i) = 3 − 6i + 4i − 8i² = 11 − 2i

  |5+12i| = √(5² + 12²) = 13

  Pass Criteria: Imaginary unit (i) and magnitude calculations adhere to Euler’s formula and Pythagorean theorem.
• Memory and Solver Functions
  Test: Store intermediate results in memory (e.g., Casio’s "M+"), then recall and use them in subsequent calculations. For solvers (e.g., TI-84’s "solve(" function), verify roots of equations like x² − 5x + 6 = 0.
