# Online Graphing Calculator: Plot your own SVG Math Graphs

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. To remove a graph, leave its text box blank.

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

(You can **resize the graph** by dragging the handle in the bottom right corner, or the right or bottom edges.)

## 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))" (without the quotation marks, of course).

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.
