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.

The following 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. 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.

Some graphs to try

The grapher 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 (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)
• 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.
