A calculator for more than arithmetic
Basic calculators stop at the four operations, but schoolwork, engineering, and science need trigonometry, logarithms, powers, and roots. This scientific calculator brings those functions together in one place, so you can evaluate an expression with parentheses and advanced operations without reaching for a physical calculator or a spreadsheet.
How to use it
- Enter your expression, using parentheses to group as needed.
- Apply functions like sine, log, or powers.
- Read the result.
What it covers
- Trigonometric functions and their inverses.
- Logarithms, exponents, powers, and roots.
- Parentheses and operator precedence for complex expressions.
Questions people ask
Degrees or radians? Trigonometry depends on the mode, so check which one is active before trusting a sine or cosine result.
