Frequently asked questions
What functions are supported?
Arithmetic, powers (^), sqrt, abs, exp, log (natural), log10, sin/cos/tan and their inverses, plus constants pi and e.
Why does 1/x have a gap?
Vertical asymptotes are detected and not joined, so the graph doesn't draw a false line across them.
Can it solve equations?
Hover where curves cross the x-axis or each other to read approximate solutions, or use our Equation Solver for exact answers.
