Online Graphing Calculator: Plot your own SVG Math Graphs

You can plot 2 functions, function 1 (in dark green) and function 2 (in magenta).

Edit your functions and then click the "Graph it" button below. To remove a graph, leave its text box blank.

(If you can't see the graph, or there is a problem, try this alternative graph plotter).

Some graphs to try

The grapher will accept any of the following functions (use the notation shown). You can copy from the examples below if you wish.

• Straight lines: (like 3x - 2)
• Polynomials: (like x^3 + 3x^2 - 5x + 2)
• Any of the trigonometric functions: sin(x), cos(x/2), tan(2x), csc(3x), sec(x/4), cot(x)
• The inverse trigonometric functions: arcsin(x), arccos(x), arctan(x), arccsc(x), arcsec(x), arccot(x)
• Exponential (e^x) and logarithm (ln(x) for natural log and log(x) for log base 10)
• Absolute value: use "abs" like this: abs(x)
• The hyperbolic functions and their inverses: sinh(x), cosh(x), tanh(x), arcsinh(x), arccosh(x), arctanh(x)
• Sign (1 if the sign is positive, −1 if the sign of the function is negative.) For example, try sign(sin(x))

In fact, you can use most of the javascript math functions, including

• ceiling: ceil(x) and round: round(x)
• square root: sqrt(x)

You can also use any combinations of the above, like ln(abs(x)).

If your graph doesn't work: Try using brackets! For example, "tan 2x" won't work. You have to put tan(2x).

More Information

The above graph is not an image (that is, it's not a .GIF, .JPG or .PNG). It is a javascript-based SVG graph. That's why we can change it so easily and not wait for an image to be created.
