Frequently asked questions
Should I use DEG or RAD?
Use DEG when working with angles measured in degrees (0-360). Use RAD when working with radians, which are the standard unit in most calculus and physics contexts.
How do I calculate powers?
Enter the base number, press xʸ (power), enter the exponent, then press =. For example: 2 xʸ 3 = gives 8.
What does n! do?
n! (factorial) multiplies all positive integers from 1 to n. For example, 5! = 5×4×3×2×1 = 120. Only works for non-negative integers.
Why does it show 'Error'?
Error appears for undefined operations like division by zero, square root of a negative number, or results that exceed the display range.
Full-featured scientific calculator with trigonometric functions (sin, cos, tan), logarithms (log, ln), powers (x², x³, xʸ), roots, factorials, and constants like π and e.
