Scientific Calculator
A full scientific calculator supporting trig functions, logarithms, exponents, and more.
About the Scientific Calculator
This scientific calculator evaluates full mathematical expressions in one step, supporting parentheses, exponents, and functions like sine, cosine, tangent, square root, logarithm, and natural log — the same operations found on a physical scientific calculator, typed as a single expression.
How It Works
The calculator parses your expression respecting standard order of operations — parentheses first, then exponents, then multiplication and division, then addition and subtraction — and evaluates recognized function names like sin(), cos(), sqrt(), and log() using your chosen angle unit for trigonometric functions.
Standard order of operations (PEMDAS) with support for +, −, ×, ÷, ^, and functions: sin, cos, tan, asin, acos, atan, sqrt, log (base 10), ln (natural log), abs, exp.
Example
Scenario: Evaluating sin(30) + sqrt(16) × 2 in degree mode.
Result: sin(30°) = 0.5, sqrt(16) = 4, so the result is 0.5 + 4×2 = 8.5.
Assumptions & Limitations
- Angle unit (degrees or radians) applies to all trigonometric functions in the expression uniformly.
- log() refers to base-10 logarithm and ln() to natural logarithm, matching standard calculator conventions.
- Does not support variables, multi-line expressions, or statistical functions — for those, use the dedicated Average or Standard Deviation calculators.
- Invalid syntax (like unmatched parentheses) will return an error rather than a partial result.
