How to Search for an Online Scientific Calculator

1. Use Keywords:
   Try search terms like:
   • “Online JavaScript scientific calculator”
   • “Interactive scientific calculator”
   • “Free web-based scientific calculator”
   • “Scientific calculator with functions”
2. Key Features to Look For:
   • Basic operations (+, -, ×, ÷)
   • Advanced functions (sin, cos, log, exponents, roots, π, e)
   • Graphing capabilities (if needed)
   • Keyboard support (type directly instead of clicking buttons)

Using an Online Scientific Calculator

If you already have one (like the one described in your message):

1. Input Methods:
   • Click buttons with your mouse.
   • Type directly using your keyboard (e.g., sqrt(9), sin(45), 2^3).
2. Common Functions:
   • Scientific Notation: Use E or e (e.g., 3e5 for 3×1053×105).
   • Parentheses: Control order of operations (e.g., (2+3)*4).
   • Constants: π (pi) or e (Euler’s number).

Example Calculation Workflow:

1. Calculate 16+3216

​+32:

• Type sqrt(16) + 3^2 ➔ Result: 4 + 9 = 13.

Calculate sin⁡(30∘)sin(30∘):

• Ensure the calculator is in degrees mode (not radians).
• Type sin(30) ➔ Result: 0.5.
