Scientific Calculator
Perform advanced math with trigonometric, logarithmic, and exponential functions.
What Is the Scientific Calculator?
A scientific calculator handles advanced mathematical operations beyond basic arithmetic. Trigonometric functions (sine, cosine, tangent), logarithms, exponents, factorials, and constants like pi and e are all available at your fingertips.
The Formula
sin(angle), cos(angle), tan(angle), log(x), ln(x), x^y, x!, e^x, 10^x, and more. Supports both degrees and radians mode.
Example
In degree mode, sin(30) equals 0.5 and cos(60) gives the same value. Log base 10 of 100 is 2. The factorial of 5 is 120 and e squared is about 7.389. The square root of 144 is exactly 12. Two to the 10th power equals 1,024, covering the five core function families.
Common Uses
Algebra, trigonometry, calculus, physics, engineering, statistics, computer science.
