About the Videnskabelig Lommeregner
The Scientific Calculator supports all standard scientific operations including trigonometric functions (sin, cos, tan and their inverses), natural and base-10 logarithms, powers, square roots, factorials, constants π and e, and a memory register. Switch between Degrees and Radians for trigonometric calculations. All computations run entirely in your browser — no data is stored or transmitted.
Understøttede funktioner
- Trigonometry — sin, cos, tan, and their inverses (arcsin, arccos, arctan) in degrees or radians
- Logarithms — natural logarithm (ln, base e) and common logarithm (log, base 10)
- Powers and roots — xʸ, x² og √x til eksponentiering og kvadratrødder
- Factorial — n! for combinatorics and probability calculations
- Constants — π (3.14159…) and e (2.71828…) for mathematical and scientific work
- Memory — store and recall values to simplify multi-step calculations
Grader vs. radianer
Trigonometric functions can work in either degrees or radians. Degrees are more intuitive for everyday geometry (a right angle is 90°), while radians are the natural unit for calculus and many physics applications (a full circle is 2π radians). This calculator lets you toggle between modes at any time.
Order of Operations
Denne lommeregner følger standard matematisk rækkefølge af operationer (BODMAS/PEMDAS): parenteser først, derefter potenser (og rødder), derefter division og multiplikation, derefter addition og subtraktion. Brug parenteser til at styre evalueringsrækkefølgen i komplekse udtryk og undgå almindelige fejl i flertrins-problemer.
