| Function | Description | Example |
|---|---|---|
| Basic Arithmetic | Addition, subtraction, multiplication, division | 5 + 3, 10 - 4, 6 × 7, 20 ÷ 5 |
| Trigonometric Functions | Calculate sine, cosine, tangent and their inverses | sin(30°), cos(45°), tan(60°) |
| Logarithms | Natural logarithm (ln) and base-10 logarithm (log) | ln(2.718), log(100) |
| Powers and Roots | Square, cube, nth powers, square root, cube root | 5², 2³, 4^0.5 (square root of 4) |
| Constants | Mathematical constants π and e | π × 2 (circumference of a circle with radius 1) |
| Factorial | Calculate the product of all positive integers less than or equal to n | 5! = 5 × 4 × 3 × 2 × 1 = 120 |
| Angle Mode | Switch between degrees (DEG) and radians (RAD) | sin(90°) in DEG mode = 1 |
Frequently Asked Questions
To switch between degrees and radians for trigonometric calculations:
- Click the "DEG" button to use degrees (default mode)
- Click the "RAD" button to use radians
The current mode will be indicated by the highlighted button. This setting affects all trigonometric functions (sin, cos, tan) and their inverses.
To calculate percentages:
- To find x% of y: Enter y, press ×, enter x, press %
- Example: To find 15% of 200, enter 200 × 15 % = 30
You can also use the percentage button for other calculations like percentage increases or decreases.
Our calculator includes memory functions to store and recall values:
- M+: Adds the current display value to memory
- M-: Subtracts the current display value from memory
- MR: Recalls the value stored in memory
These functions are useful for complex calculations where you need to store intermediate results.
For powers and roots:
- x²: Enter a number and press the x² button to square it
- x³: Enter a number and press the x³ button to cube it
- x^y: Enter the base number, press x^y, enter the exponent, press =
- √x: Enter a number and press the √x button for square root
- ³√x: Enter a number and press the ³√x button for cube root
For other roots, you can use the power function with fractional exponents. For example, to find the 4th root of 16, calculate 16^(1/4).
Yes, our scientific calculator supports keyboard input for faster calculations:
- Number keys (0-9): Enter numbers
- Operators (+, -, *, /): Perform basic arithmetic
- Enter key: Calculate result (equivalent to "=")
- Backspace key: Delete the last character
- Delete or Escape key: Clear the display (equivalent to "AC")
- Decimal point (.) key: Enter decimal point
- p key: Enter π (pi)
- e key: Enter e (Euler's number)
Note that some advanced functions may not have direct keyboard shortcuts and require using the on-screen buttons.
