How to Use
Type any function using x as the variable. Supports: + - * / ^ (power), sin, cos, tan, log (base 10), ln (natural), sqrt, abs, pi, e. Plot up to 3 functions simultaneously. Hover over the graph to see exact coordinates. Zoom in and out or drag to pan.
FAQ
What functions can I graph?
Any function of x: polynomials (x^2, x^3-3*x), trigonometric (sin(x), cos(x), tan(x)), logarithmic (log(x), ln(x)), exponential (2^x, e^x), and combinations of these.
Can I plot multiple functions?
Yes — up to 3 functions at once. Each gets a different color so you can compare them visually and find intersections.
Does it work on my phone?
Yes — the calculator is fully responsive and works on any device with a modern browser.
