How to Calculate Scientific Calculator

What is Scientific Calculator?

A scientific calculator extends basic arithmetic with trigonometric functions, logarithms, exponentials, roots, and statistical operations. It is essential for science, engineering, and mathematics beyond basic arithmetic.

Step-by-Step Guide

  1. 1Trigonometric functions: sin, cos, tan and their inverses (arcsin, arccos, arctan)
  2. 2Logarithms: log₁₀ (common log), ln (natural log base e)
  3. 3Exponentials: 10^x, e^x
  4. 4Scientific notation: 6.022 × 10²³ (Avogadro's number)
  5. 5Memory functions: store and recall intermediate results

Worked Examples

Input
sin(45°)
Result
0.7071 (= √2/2)
Ensure calculator is in DEG mode, not RAD
Input
log(1000)
Result
3
log₁₀(10³) = 3
