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
Trigonometrysin, cos, tan, asin, acos, atancos(60°) = 0.5
Logarithmslog (base 10), ln (natural)ln(e) = 1
Exponentsx², x³, xʸ, eˣ, 10ˣ2⁵ = 32
Roots & Powers√x, ∛x, x^(1/y)∛27 = 3

How to Use (Quick Guide)

  1. Enter number → function (e.g., 90 → sin)
  2. Switch DEG/RAD for angles
  3. Use parentheses for complex: (2+3)×5
  4. Memory: M+ to store, MR to recall
  5. 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
