A full scientific calculator in your browser: trigonometry with switchable degree and radian modes, logarithms, powers, roots, factorials and constants like ฯ and e, plus a history of your recent calculations. Everything computes instantly on your device.
Frequently asked questions
How do I switch between degrees and radians?
Use the DEG/RAD toggle before evaluating trig functions. In DEG mode, sin(90) = 1; in RAD mode, sin(ฯ/2) = 1. An unexpected trig result is almost always a mode mismatch, so check the toggle first.
What functions are included?
Sine, cosine and tangent, logarithms (natural and base-10), exponents and powers, square roots, factorials, reciprocals, and the constants ฯ and e โ the standard set found on a physical scientific calculator.
Does it keep a history of calculations?
Yes. Recent calculations are listed so you can check your work or reuse an earlier result without retyping it.
Is my usage tracked or sent anywhere?
No. All calculations run locally in your browser โ nothing you enter is transmitted to a server.
