supports + − × ÷, ^, sqrt, sin, cos, tan, log, ln, π, e
The default scenario, worked through
On the values this calculator opens with, the result is 12. Alongside it, Mode comes out at Radians. Change any field and every figure updates as you type.
Common questions
What functions are supported?
Trigonometry (sin, cos, tan and inverses), logarithms (log, ln), square root, exponentials, powers and the constants π and e.
How do I do powers and roots?
Use ^ for powers (2^3 = 8) and sqrt() for square roots. Fractional powers give other roots.
Degrees or radians?
Toggle the DEG/RAD button. Trig functions use whichever mode is shown.
