Trigonometric Functions Explained
Sine (sin): Ratio of opposite side to hypotenuse in a right triangle. Used in wave analysis, oscillations, and periodic functions.
Cosine (cos): Ratio of adjacent side to hypotenuse. Used in rotations, projections, and signal processing.
Tangent (tan): Ratio of opposite to adjacent side. Used in slopes, angles, and gradients.
Logarithmic Functions
Log (Base 10): Common logarithm used in engineering, decibels, and pH scales. log₁₀(100) = 2
Ln (Natural Log): Logarithm with base e, used in calculus, exponential growth, and finance. ln(e) = 1

Tips for Scientific Calculations
- Use parentheses to ensure correct order of operations: (2+3)*4 ≠ 2+3*4
- Trigonometric functions typically use radians in scientific contexts
- Logarithms require positive arguments; log(0) is undefined
- Double-check complex calculations for accuracy
- Use CE (Clear Entry) for single errors and C for complete reset
Order of Operations (PEMDAS)
Our calculator follows standard mathematical order: Parentheses → Exponents → Multiplication/Division → Addition/Subtraction
