🧮 What is a Scientific Calculator?

A Scientific Calculator is a powerful calculator used to solve advanced mathematical problems beyond basic arithmetic.

👉 It is used for:

• Algebra & equations
• Trigonometry (sin, cos, tan)
• Logarithms (log, ln)
• Powers & roots
• Scientific and engineering calculations

🎯 How to Use a Scientific Calculator

1. Enter Numbers or Expression
   
   • Example: 2 × sin(30)
2. Select Functions
   
   • sin, cos, tan
   • log, ln
   • x², √x, xʸ
3. Press “=” or Calculate Button
4. View Result

📊 Common Functions

👉 Trigonometry

• sin(x), cos(x), tan(x)

👉 Logarithms

• log(x), ln(x)

👉 Powers & Roots

• x², x³, √x, xʸ

👉 Constants

• π (pi), e (Euler’s number)

📊 Example

👉 Expression: sin(30°)

➡️ Result = 0.5

👉 Expression: log(100)

➡️ Result = 2
