How to Use
Basic Operations:
Use +, −, ×, ÷ buttons for arithmetic. Example: 45 + 23 = 68
Trigonometry:
sin, cos, tan functions work in degrees. Example: sin(30) = 0.5
Logarithms:
log (base 10) and ln (natural log). Example: log(100) = 2
Powers:
x² for square, x³ for cube. Example: 5² = 25, 2³ = 8
Constants:
π (pi ≈ 3.14159) and e (Euler's number ≈ 2.71828)
Practical Examples
Engineering
Calculate roof slope: tan(30°) = 0.577
Input: 30 → tan → Result: 0.577
Geometry
Circle circumference: 2 × π × 5 = 31.42
Input: 2 × π × 5 = Result: 31.42
Statistics
Standard deviation uses √(variance)
Input: 25 → √ → Result: 5
Finance
Compound interest: 1000 × e^0.05 = 1051.27
