Scientific Calculator — Advanced Math at Your Fingertips

This free online scientific calculator handles everything from basic arithmetic to advanced scientific functions. Compute trigonometric functions (sin, cos, tan and their inverses), logarithms (log base 10 and natural log), square roots, exponents, and more. Toggle between degree and radian modes, use memory functions (MC, MR, M+, M−), and view your calculation history. Whether you're a student solving homework, an engineer doing quick calculations, or anyone who needs more than a basic calculator, this tool has you covered.

Frequently Asked Questions

When should I use degrees vs radians?

Use degrees for everyday angles (90°, 45°, 360°). Use radians for calculus, physics, and engineering where π-based measurements are standard (π/2, π/4, 2π).

What is the difference between log and ln?

log is the common logarithm (base 10), used in chemistry and engineering. ln is the natural logarithm (base e ≈ 2.718), widely used in calculus, statistics, and physics.

How do memory functions work?

M+ adds the current display value to memory, M− subtracts it, MR recalls the stored value, and MC clears memory. Use these to store intermediate results during multi-step calculations.

What does the |x| function do?

|x| is the absolute value function. It returns the non-negative value of a number: |−5| = 5 and |5| = 5.
