Online Graphing Calculator: Plot your own SVG Math Graphs

NOTE: It appears that you may not be using a compatible browser for this. Please use either Firefox, Chrome, Safari or Opera. These browsers can render SVG graphs successfully, while other browsers (like Internet Explorer) require a plugin.

It will only work in Internet Explorer if you have Adobe’s SVG Viewer plugin.

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

Edit your functions and then click the "Graph it" button below.

(If you can't see the graph below, try this alternative graph plotter).

Some graphs to try

The graphing calculator will accept any of the following functions (use the notation shown):

• 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. For log base 10 you need to put ln(x)/ln(10). I'm using Change of Base rule.)
• 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 (returns 1 if the sign of the function value 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)
• random: random(x);
• square root: sqrt(x)

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

You can just have one graph if you want - just leave one of the "function" boxes empty.

More Information

The above illustration is an example of vector graphics - images that are made using vectors.

The graph is not an image (that is it's not a .GIF or .JPG). It is a scalable vector graphics text file which is being rendered by your browser as a picture.
