Frequently Asked Questions
What functions does this scientific calculator support?
This calculator supports basic arithmetic (addition, subtraction, multiplication, division), trigonometric functions (sin, cos, tan), logarithms (log base 10, natural log), powers and roots (x squared, square root, x to the power of n), absolute value, factorials, percentage, Euler's number (e), pi (π), and scientific notation (EXP). It also stores the last answer for reuse in subsequent calculations.
What is the difference between DEG and RAD mode?
DEG (degrees) and RAD (radians) are two ways of measuring angles. In degree mode, a full circle is 360 degrees, and sin(90) = 1. In radian mode, a full circle is 2π radians (~6.283), and sin(π/2) = 1. Most everyday calculations use degrees, while radians are standard in mathematics, physics, and calculus. Toggle between modes using the DEG/RAD button.
How do I calculate factorials?
Enter the number you want the factorial of, then press the n! button. For example, to calculate 5!, press 5 then n!. The result is 120 (5 × 4 × 3 × 2 × 1). Factorials grow very quickly — this calculator supports factorials up to 170! (beyond which the result exceeds JavaScript's maximum number). Factorial is only defined for non-negative integers.
