A full scientific calculator with trigonometry (sin, cos, tan), logarithms, powers, roots, and memory functions. All calculations happen instantly in your browser.
Fill in the details and
your result appears here.
Use the on-screen buttons or your keyboard. Number keys, operators, and Enter all work.
Click sin, cos, log etc. — they open a bracket automatically. Close it with ) before pressing =.
M+ adds current result to memory. MR recalls it. MC clears memory.
This calculator uses JavaScript's built-in Math library for all scientific functions:
Trig functions (sin, cos, tan) take degrees as input — the calculator converts to radians internally using x × π ÷ 180.
Degrees. sin(90) returns 1, not sin(1.5708). The calculator automatically converts degrees to radians internally for all trig functions.
Click sin, then 30, then ), then =. Result: 0.5.
Click xʸ — it opens Math.pow(. Type the base, a comma, the exponent, then close with ) and press =. E.g. Math.pow(2,8) = 256.
Yes. Number keys, +, -, *, /, (, ), . and Enter all work. Backspace deletes. Escape clears.
EXP (exponent) enters scientific notation. Pressing 3 EXP 4 enters 3 × 10⁴ = 30,000. It is faster than typing out the full number and avoids entry errors with very large or very small values.
