About the Scientific Calculator
This comprehensive scientific calculator provides a wide range of mathematical functions essential for students, engineers, and scientists. It can perform both basic arithmetic operations and advanced mathematical calculations including trigonometric, logarithmic, and exponential functions.
Features:
- Basic Operations: Addition, subtraction, multiplication, division, and percentage calculations
- Trigonometric Functions: sin, cos, tan with inverse functions (sin⁻¹, cos⁻¹, tan⁻¹)
- Logarithmic Functions: Base-10 logarithm (log) and natural logarithm (ln)
- Exponential Functions: eˣ, 10ˣ, 2ˣ, and general power function (xʸ)
- Root Functions: Square root (√) and nth root calculations
- Special Functions: Factorial (x!), absolute value (|x|), and constants (π, e)
- Memory Functions: Store and recall values with memory operations (MC, MR, M+, M-)
- Flexible Settings: Choose between degrees and radians for trigonometric functions
- Precision Control: Adjust display precision from 2 to 10 decimal places
- Calculation History: View your recent calculations for reference
How to Use:
To use this calculator, simply click the buttons or type directly into the display. You can perform complex calculations by combining multiple operations. Use parentheses to specify the order of operations. The calculator will automatically evaluate expressions according to standard mathematical precedence rules.
Examples:
- Basic Calculation: 5 + 3 × 2 = 11 (multiplication has higher precedence than addition)
- With Parentheses: (5 + 3) × 2 = 16 (parentheses change the order of operations)
- Trigonometric Function: sin(30) = 0.5 (when in degree mode)
- Exponential Function: 2^3 = 8 (use the xʸ button)
- Logarithm: log(100) = 2 (base-10 logarithm)
For more complex calculations, combine functions like sin(cos(tan(45))) or use memory functions to store intermediate results. The calculator supports chaining operations, so you can continue calculations with the previous result by simply entering a new operator.
