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.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

How to Scientific Calculator

▾
  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

▾
Example 1
Given:sin(45°)
Result:0.7071 (= √2/2)

Ensure calculator is in DEG mode, not RAD

Example 2
Given:log(1000)
Result:3

log₁₀(10³) = 3
