Scientific Calculator

This is a free online Scientific Calculator for complex mathematical, engineering, and scientific calculations. It supports trigonometric, logarithmic, exponential, and memory functions, making it essential for general users, students, engineers, and professionals.

Note: Use parentheses to control calculation order. MC before starting new calculations to avoid memory errors. Need radians? Multiply degrees by π/180 (sin(30° × π/180)

Functions & How to Use Them

1. Basic Operations

  • C: Clear all inputs (reset calculator)
  • ← (Backspace): Delete the last digit
  • =: Get the result

2. Trigonometric Functions (DEG Mode)

  • sin: Sine of an angle (sin(30) = -0.98803162409)
  • cos: Cosine of an angle (cos(60) = -0.95241298041)
  • tan: Tangent of an angle (tan(45) = 1.61977519054)

3. Logarithmic & Exponential Functions

  • log: Base-10 logarithm (log(10) = 1)
  • ln: Natural logarithm (base e) (ln(7.389) = 2)
  • exp: Exponential function (eˣ) (exp(1) = 2.718)

4. Roots & Powers

  • √: Square root (√(25) = 5)
  • x³: Cube of a number (2 x³ = 8)
  • ³√: Cube root (³√(27) = 3)

5. Constants

  • π: Pi (3.1416)

  • e: Euler’s number (2.71828)

6. Memory Functions

  • MC: Memory Clear (reset stored value)

  • MR: Memory Recall (display stored value)

  • M+: Add current value to memory

  • M-: Subtract current value from memory

7. Parentheses & Percentage

  • ( ): Group calculations ((2+3)×4 = 20)

  • %: Percentage (50 + 10% = 55)

Why Use Scientific Calculator?

  1. This Calculator performs complex calculations instantly.
  2. Store and recall values for multi-step problems.
  3. Clean design with keyboard support.
  4. Helps students learn trigonometry, logarithms, and exponents.

Frequently Asked Questions (FAQs)

1. How do I switch between DEG and RAD modes?

Currently, Our Scientific Calculator is in DEG (Degrees) mode. If you need radians, manually convert (sin(30° in DEG = sin(0.5236 rad)).

2. Why does log(100) return 2?

Because log is base-10, and 10² = 100.

3. How do I use memory functions effectivel

  • Store a value: 5 M+

  • Recall it later: MR → displays 5

  • Add another number: 3 M+ → now stored value is 8

  • Clear memory: MC

4. Can I type directly instead of clicking buttons?

Yes, You can because our calculator supports keyboard for numbers and operators (+, -, *, /).
