Scientific Calculator
A full-featured scientific calculator with trig functions, logarithms, exponents, and more.
Note: Trigonometric functions use degrees. Use π and e for precise calculations.
What It Does
This calculator handles everything from basic math (addition, multiplication) to advanced functions like trigonometry (sin, cos, tan), logarithms (log, ln), exponents (x², x³, xʸ), and roots (√). Use parentheses for complex expressions, switch between degrees and radians for angles, and access constants like π and e.
Useful for homework, physics problems, engineering calculations, or any time you need more than a basic calculator.
FAQ
How do I use trigonometric functions?
Enter the angle, then hit sin, cos, or tan. Make sure you're in the right mode—degrees for most school problems, radians for calculus.
What's the difference between log and ln?
'log' is base-10, 'ln' is natural log (base e). For most science and math, you'll use ln. For things like pH or decibels, use log.
How do I calculate powers and roots?
Enter your number, then hit x² for square, x³ for cube, or x^y for any power. For square root, enter the number and press √.
What's C vs CE?
'C' clears everything and starts over. 'CE' just clears your last entry if you messed up. Use CE to fix typos without losing your whole calculation.
