Scientific Calculator Function Cheatsheet
Scientific calculators handle complex algebraic, trigonometric, logarithmic, and exponential operations beyond basic arithmetic.
| Function | Button Key | Mathematical Meaning | Example |
|---|---|---|---|
| Sine / ArcSine | sin / sin⁻¹ | Trigonometric sine ratio (opposite / hypotenuse) | sin(30°) = 0.5 |
| Cosine / ArcCosine | cos / cos⁻¹ | Trigonometric cosine ratio (adjacent / hypotenuse) | cos(60°) = 0.5 |
| Tangent / ArcTangent | tan / tan⁻¹ | Trigonometric tangent ratio (opposite / adjacent) | tan(45°) = 1 |
| Logarithm (Base 10) | log | Common logarithm (power of 10) | log(1000) = 3 |
| Natural Logarithm | ln | Logarithm to natural base e (e ≈ 2.71828) | ln(e) = 1 |
| Exponents & Roots | xʸ / √ | Raises base to power y or evaluates square root | 2^10 = 1024, √(144) = 12 |
| Factorial | n! | Product of all positive integers ≤ n | 5! = 120 |
Frequently Asked Questions
DEG mode measures angles in degrees (360° for a full circle, e.g. sin(30°) = 0.5). RAD mode measures angles in radians (2π for a full circle, e.g. sin(π/6) = 0.5). Be sure to select DEG for standard geometry or RAD for calculus and physics problems.
