Scientific Calculator
Perform advanced mathematical and engineering calculations instantly with this free online scientific calculator.
What is a Scientific Calculator?
A scientific calculator is a specialized type of calculator designed to help solve complex mathematical, engineering, and scientific problems. Unlike a basic calculator, which only handles addition, subtraction, multiplication, and division, a scientific calculator provides functions like trigonometry (sin, cos, tan), logarithms, exponents, roots, factorials, and more.
Key Features
- Trigonometric functions: sin, cos, tan, and their inverses
- Logarithmic and exponential calculations
- Power and root operations
- Factorials and combinatorics
- Constants like π and e
- Support for parentheses and complex expressions
Formula Examples
Common formulas you can compute with this calculator include:
- Trigonometry: sin(45°) = 0.7071
- Logarithm: log(100) = 2
- Exponents: 2^3 = 8
- Square root: sqrt(16) = 4
Use Cases
Students and professionals use scientific calculators for a wide range of tasks:
- Calculating angles and distances in engineering projects
- Solving logarithmic equations in chemistry and physics
- Performing complex financial projections (try also our ROI Calculator or Loan Calculator for related computations)
- Analyzing health metrics along with tools like our BMI Calculator or Calorie Calculator
How to Use This Calculator
Simply type your expression into the input field. Examples include:
sin(30)log(10) + 5^2sqrt(64) - 4!
Then click Calculate to see the result instantly. This tool uses a robust math parsing library to handle nested operations and follows standard mathematical order of operations (PEMDAS/BODMAS).
Benefits
- Accessible online from any device
- No need to purchase expensive hardware calculators
- Always up-to-date with the latest functions
Limitations
This calculator is designed for general educational and professional use. For industry-certified precision in critical engineering or compliance scenarios, cross-check with approved equipment or standards, such as those outlined by NIST.
