Scientific Calculator: Full-Featured Math Powerhouse
Advanced calculator with 50+ functions — trig, logs, exponents, factorials, roots, memory, and more. Perfect for students, engineers, scientists, and finance pros. No ads. No tracking.
Example: sin(30°) = 0.5 | log₁₀(100) = 2 | 5! = 120 | √64 = 8.
Core Scientific Functions
| Category | Functions | Example |
|---|---|---|
| Trigonometry | sin, cos, tan, asin, acos, atan | cos(60°) = 0.5 |
| Logarithms | log (base 10), ln (natural) | ln(e) = 1 |
| Exponents | x², x³, xʸ, eˣ, 10ˣ | 2⁵ = 32 |
| Roots & Powers | √x, ∛x, x^(1/y) | ∛27 = 3 |
| Factorials & Constants | n!, π, e | 5! = 120 |
| Memory | MC, MR, M+, M- | Store & recall values |
How to Use (Quick Guide)
- Enter number → function (e.g., 90 → sin)
- Switch DEG/RAD for angles
- Use parentheses for complex: (2+3)×5
- Memory: M+ to store, MR to recall
- Clear: C (entry) or AC (all)
Real-World Examples
Physics
Force = m×a → 5×9.81 = 49.05 N
Finance
Future value: 1000×(1+0.05)⁵ = 1276.28
Math Class
sin(45°)×√2 = 1
Engineering
log₁₀(1000) = 3 → 60 dB
