- ✅ Trigonometric functions such as sine (sin), cosine (cos), and tangent (tan).
- ✅ Constants support like π (pi).
- ✅ Memory functions (MC, MR, M+, M−) to store and recall values.
- ✅ Error handling that prevents invalid calculations.
- ✅ Clean and responsive interface that works well on both desktop and mobile.
Step-by-Step Instructions on How to Use the Tool
Follow these simple steps to make the most out of the scientific calculator:
1. Access the Calculator
Open the calculator in your browser. You’ll see a clean display screen and buttons for digits, operators, and functions.
2. Enter Numbers
Click on number buttons (0–9) to input values. They will appear on the display.
3. Perform Arithmetic Operations
- Use + for addition, − for subtraction, × for multiplication, and ÷ for division.
- Use mod for modulus (remainder after division).
4. Use Advanced Functions
- √ – square root of a number.
- ln – natural logarithm.
- log – base-10 logarithm.
- xʸ – raise a number to a power.
- eˣ – exponential function.
- π – insert pi constant.
- x! – factorial of a number.
5. Apply Trigonometric Functions
- Use sin, cos, or tan followed by parentheses and the value. Example:
sin(30).
6. Memory Functions
- MC (Memory Clear): resets memory.
- MR (Memory Recall): retrieves stored value.
- M+: adds the displayed result to memory.
- M−: subtracts the displayed result from memory.
7. Final Calculation
Press the = button to evaluate the expression. The result appears on the display.
8. Clear and Delete
- Use C to reset the screen.
- Use DEL to remove the last input.
Practical Example
Let’s say you want to calculate the following:
Expression:
(5×3)+√(16)+sin(30°)(5 × 3) + √(16) + sin(30°)(5×3)+√(16)+sin(30°)
Steps:
- Press
5 × 3 =→ Result: 15 - Add
√(16)→ Result: 15 + 4 = 19 - Add
sin(30)→ Result: 19 + 0.5 = 19.5
This shows how quickly you can perform multi-step scientific calculations with the tool.
