How to Use the Scientific Calculator
Basic Operations
Our scientific calculator supports all basic arithmetic operations: addition (+), subtraction (-), multiplication (×), and division (/). Simply click the numbers and operators to build your expression.
Advanced Functions
Access trigonometric functions (sin, cos, tan), logarithms (log, ln), exponents (^), square roots (√), and factorials (!) with dedicated buttons. Use parentheses to control calculation order.
Constants
Quickly insert mathematical constants like π (pi) and e (Euler's number) into your calculations with dedicated buttons.
Memory Functions
Store values in memory for later use:
- MS: Store the current display value in memory
- MR: Recall the value stored in memory
- MC: Clear the memory
- M+: Add the current display value to memory
Unit Conversion
Convert between degrees and radians using the D→R and R→D buttons. This is especially useful when working with trigonometric functions.
Calculation History
Review your previous calculations in the history panel. You can clear the history at any time using the "Clear History" button.
Pro Tips:
- Use parentheses to group operations and ensure correct calculation order
- Take advantage of the real-time calculation feature to check intermediate results
- Use the memory functions to store frequently used values
- Remember that trigonometric functions use radians by default
