A scientific calculator is an advanced computational tool designed to handle complex mathematical operations beyond basic arithmetic. It includes functions for trigonometry (sine, cosine, tangent), logarithms, exponents, roots, factorials, and statistical calculations. Unlike standard calculators, scientific calculators support order of operations, parentheses for complex expressions, and memory functions for storing values. Many modern versions also handle constants like π and e, unit conversions, and equation solving. Essential for students and professionals in STEM fields, scientific calculators provide precision for advanced mathematics, physics, engineering, and scientific research while maintaining a user-friendly interface that balances functionality with accessibility.
