About Scientific Calculator

Scientific calculator provides advanced mathematical functions beyond basic arithmetic.

Available Functions:

  • Trigonometric: sin, cos, tan (radians/degrees)
  • Logarithmic: log (base 10), ln (natural log)
  • Exponential: x², x³, xʸ (power)
  • Constants: π (pi), e (Euler's number)
  • Roots: √ (square root)

Usage Tips:

  • Use parentheses for complex expressions
  • Switch between radians and degrees for trig functions
  • View calculation history for reference
  • Use ^ for power operations

This calculator supports basic scientific functions. For more advanced calculations, consider specialized mathematical software.

How our scientific calculator works

1

Type an expression

Enter a math expression using standard notation: sin(30), log(100), 2^10, sqrt(144), or complex combinations like (5+3)*sqrt(9).

2

Use advanced functions

Switch between degrees and radians. Access trig (sin/cos/tan), inverse trig, logs (log/ln), exponents, roots, factorials, and constants like pi and e.

3

Read the result with history

The current answer shows at the top. Scroll down for a running history of every calculation in the session so you can audit and reuse intermediate values.

Key things to know about our scientific calculator:

  • Degrees vs radians: Trig functions in math and physics classes use radians; geometry and navigation use degrees.
  • Fraction and decimal work: For step-by-step fraction and decimal work, pair with our fraction calculator and decimal to fraction calculator.
  • Same engine as classrooms: The scientific calculator is the same engine used in physics, engineering, and finance courses worldwide.
