Scientific Calc
Advanced Scientific Functions
A scientific calculator goes beyond basic arithmetic to handle trigonometry, logarithms, and exponential functions, making it essential for students, engineers, and scientists.
Key Functions
- Trigonometry: sin, cos, tan (and their inverses: asin, acos, atan). Used in geometry, physics, and engineering.
- Logarithms: log (base 10) and ln (natural log, base e). Used in measuring sound (decibels), earthquakes (Richter scale), and pH.
- Exponents: x^y, e^x, and square roots. Used in growth and decay models.
- Factorial: n! (e.g., 5! = 5×4×3×2×1). Used in probability and statistics.
Degrees vs. Radians
This is the most common mistake. Always ensure your calculator is in the correct mode.
- Degrees: A full circle is 360°. Used in basic geometry and navigation.
- Radians: A full circle is 2π. Used in higher mathematics and calculus.
FAQ
What is 'e'?
Euler's number (approx 2.718) is a mathematical constant used in calculating compound interest and natural growth rates.
