FAQ
Graph calculator questions
Do I need to type y = before every equation?
No. For standard graphs, enter the expression only. The page keeps the graph list clean and does not force an extra y = label.
Why does x² + y² = 25 not plot in standard mode?
That is an implicit relation, not a single function of x. Use parametric mode with x(t) = 5cos(t) and y(t) = 5sin(t), or rewrite it as upper and lower functions.
Can I graph polar and parametric equations?
Yes. Switch the mode, enter r(θ) or x(t)/y(t), and the engine will plot the curve with the same graph canvas.
Does it support roots and intersections?
Roots, intersections, asymptote hints, and derivative overlays are calculated from the visible equations.
Can I use complex expressions like |x| or x²?
Yes. The parser normalizes brackets, superscripts, square roots, absolute values, degrees, and implicit multiplication.
