What can a scientific calculator do?
A scientific calculator handles the math that goes beyond basic addition and subtraction: trigonometry, logarithms, exponentials, factorials, and more. Engineers, scientists, students, and finance pros use them daily.
Trigonometric functions
sin, cos, tan and their inverses (asin, acos, atan). Make sure you're using the right mode — radians for math/engineering, degrees for everyday geometry.
Radian ↔ degree: radians = degrees × π / 180
Logarithms
ln is the natural log (base e ≈ 2.718). log is base-10. Both are common in physics, finance (compound interest), and statistics.
Exponentials
x^y raises x to the power y. e^x is the exponential function, used heavily in growth models and continuous compounding.
Factorial
n! = n × (n−1) × (n−2) × ... × 1. Used in probability and permutations. 5! = 120. 10! = 3,628,800.
Frequently asked questions
Does this work offline?
Yes. All math happens locally. After the first load, it works offline.
Radians vs degrees?
Click the DEG/RAD selector. Math/engineering usually uses radians; geometry uses degrees.
Can I see the history?
Yes. The small line above the main display shows the previous expression.
