# About This Calculator

A scientific calculator is an advanced calculation tool that goes beyond basic arithmetic to handle trigonometric functions, logarithms, exponentials, roots, and complex mathematical expressions. It's essential for students, engineers, scientists, and anyone working with advanced mathematics.

Scientific calculators are indispensable in physics (calculating trajectories, forces), chemistry (pH calculations, reaction rates), engineering (structural analysis, circuit design), statistics (probability distributions), and advanced mathematics. They handle operations that would be extremely tedious or impossible to compute manually.

This calculator supports trigonometric functions (sin, cos, tan), logarithms (log, ln), exponentials (e^x, x^y), square roots, and mathematical constants (π, e). It follows standard order of operations (PEMDAS) and allows parentheses for complex expressions. Note: trigonometric functions currently operate in radians mode.

Whether you're solving physics problems, analyzing data, or working through calculus homework, this tool provides the computational power you need. It's perfect for quick calculations, verifying manual work, or exploring mathematical relationships without needing a physical calculator.

How To Use

  1. Use the keypad to enter your expression.
  2. Press = to calculate.
  3. Use AC to clear all and DEL to backspace.

Frequently Asked Questions

Does it support degrees?+

Currently, trigonometric functions expect radians. To convert degrees to radians, multiply by π/180. For example, 30° = 30 × π/180 = 0.5236 radians. Alternatively, calculate in degrees then convert: sin(30°) = 0.5.

What's the difference between log and ln?+

log (common logarithm) uses base 10: log(100) = 2 because 10² = 100. ln (natural logarithm) uses base e (≈2.718): ln(e) = 1 because e¹ = e. In science and calculus, ln is more common. In engineering, log is often used.

How do I calculate powers and roots?+

For powers, use the ^ button: 2^3 = 8. For square roots, use √: √(16) = 4. For other roots, use fractional exponents: cube root of 8 = 8^(1/3) = 2. Fourth root of 16 = 16^(1/4) = 2.

What is 'e' and why is it important?+

e ≈ 2.71828 is Euler's number, the base of natural logarithms. It appears in continuous growth/decay (compound interest, population growth, radioactive decay), calculus (derivative of e^x is e^x), and probability. It's as fundamental as π.

How do I enter complex expressions with parentheses?+

Use parentheses to group operations: (5 + 3) × 2 = 16 (not 11). For nested expressions: ((2 + 3) × 4) + 1 = 21. The calculator follows PEMDAS order: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

Why do I get unexpected results with trig functions?+

Most likely you're entering degrees when the calculator expects radians. sin(90) in radians ≈ 0.894, but sin(90°) = 1. Convert degrees to radians first: 90° = 90 × π/180 ≈ 1.571 radians, so sin(1.571) ≈ 1.
