Scientific Calculator
Your tool for advanced calculations.
About This Calculator
The Scientific Calculator is a powerful online tool designed for advanced mathematical calculations. It supports basic arithmetic, trigonometric functions (sin, cos, tan), logarithms, square roots, and more complex mathematical operations.
Perfect for students, engineers, scientists, and anyone who needs to perform complex calculations without specialized software. The calculator handles parentheses, order of operations, and provides accurate results for all supported functions.
Formula & Calculation Method
Supported Operations: The calculator uses standard mathematical operations and functions.
Basic Operations:
- Addition (+), Subtraction (-), Multiplication (*), Division (/)
- Exponentiation (^ or **)
- Parentheses for grouping: ( )
Advanced Functions:
- Trigonometric: sin(), cos(), tan() (radians)
- Logarithms: log() (base 10), ln() (natural log)
- Square root: sqrt()
- Constants: π (pi), e (Euler's number)
All calculations follow standard mathematical order of operations (PEMDAS/BODMAS).

Frequently Asked Questions
What functions are supported?
The calculator supports basic arithmetic (+, -, *, /), exponentiation (^), trigonometric functions (sin, cos, tan), logarithms (log, ln), square root (sqrt), and mathematical constants (π, e).
How are trigonometric functions calculated?
Trigonometric functions (sin, cos, tan) accept angles in radians. To convert degrees to radians, multiply by π/180. For example, sin(30°) should be entered as sin(30*π/180).
Can I use parentheses in my expressions?
Yes! You can use parentheses to group operations and control the order of calculations. For example: (2+3)*4 = 20.
What is the difference between log and ln?
log() is the base-10 logarithm (common logarithm), while ln() is the natural logarithm (base e). For example, log(100) = 2, and ln(e) = 1.
