Frequently asked questions
What can this calculator do?
Everything a scientific calculator does (trig, logs, roots, powers) plus CAS operations: symbolic derivatives, indefinite integrals, factoring, expanding and exact equation solving. The graph tab plots your function with its derivative overlaid.
How does graphing work?
Enter an expression and press [graph]. Drag to pan, scroll (or use +/−) to zoom. With “overlay derivative” on, the function (green on the Korean site, blue here) and its derivative (orange) are drawn together.
How do I enter expressions?
Use the keypad or type directly — x^2 becomes a proper exponent and / becomes a fraction, just like a TI-Nspire.
Does it use radians or degrees?
Radians. For degrees, multiply by π/180 — sin(30°) is sin(30π/180) = 1/2.
Are there problems it cannot solve?
Yes — some integrals have no closed form (like e^(x²)) and high-degree equations have no general symbolic solution. The calculator tells you when no result can be found.
Engine: the open-source Nerdamer CAS (symbolic math, compiled graph functions) with MathLive input — everything runs locally in your browser. Trig functions use radians.
