Scientific Calculator

This is a full-featured scientific calculator that handles everything from basic arithmetic to trigonometric functions, logarithms, powers, roots, and mathematical constants like π and e. Operations are chained in real time, and the display shows your current expression so you can see what you're computing — not just the last result. It's built for the moment when your phone's calculator app isn't quite enough.

All standard mathematical operations: +, -, ×, ÷, √, x², xⁿ, sin, cos, tan, log, ln, π, e

Use this when you need trig functions (sin, cos, tan) for geometry or physics, logarithms for chemistry or finance calculations, or powers and roots for anything from area calculations to compound growth. It's also handy for checking manual calculations, helping students work through problems step by step, or any time you need a quick scientific computation without opening a spreadsheet.
