Advanced math functions with trigonometry, logarithms, and constants
The Scientific Calculator provides advanced mathematical functions including trigonometry, logarithms, constants, and complex expressions. All calculations run locally in your browser — no data is transmitted to any server.
Zero server lag. All calculations run locally on your device for maximum speed.
Your data never leaves your device. No uploads, no servers, no tracking.
Yes. Use ( and ) buttons to group expressions and control order of operations.
The calculator uses JavaScript double-precision floating point arithmetic, which is accurate for most everyday calculations.
By default, sin, cos, and tan use radians. Convert degrees to radians manually if needed (radians = degrees × p/180).
Available functions include sin, cos, tan, log (base 10), ln (natural log), sqrt (square root), p (pi), e (Euler's number), and ans (previous answer).
