Function Grapher is a full featured Graphing Utility that supports graphing up to 5 functions together.

You can also save your work as a URL (website link).

Usage To plot a function just type it into the function box.

Use "x" as the variable like this:

Examples:

sin(x) 2x−3 cos(x^2) (x−3)(x+3) Zooming and Re-centering

To zoom, use the zoom slider. To the left zooms in, to the right zooms out. When you let go of the slider it goes back to the middle so you can zoom more.

You can click-and-drag to move the graph around.

If you just click-and-release (without moving), then the spot you clicked on will be the new center

To reset the zoom to the original click on the Reset button.

Using "a" Values

There is a slider with "a =" on it. You can use "a" in your formula and then use the slider to change the value of "a" to see how it affects the graph.

Examples:

x^a 2x−3a sin(ax) All Functions Operators + Addition operator - Subtraction operator * Multiplication operator / Division operator ^ Exponent (Power) operator Functions sqrt Square Root of a value or expression. sin sine of a value or expression cos cosine of a value or expression tan tangent of a value or expression asin inverse sine (arcsine) of a value or expression acos inverse cosine (arccos) of a value or expression atan inverse tangent (arctangent) of a value or expression sinh Hyperbolic sine (sinh) of a value or expression cosh Hyperbolic cosine (cosh) of a value or expression tanh Hyperbolic tangent (tanh) of a value or expression exp e (Euler's number) raised to the power of a value or expression ln The natural logarithm of a value or expression log The base−10 logarithm of a value or expression floor Returns the largest (closest to positive infinity) value that is not greater than the argument and is equal to a mathematical integer. ceil Returns the smallest (closest to negative infinity) value that is not less than the argument and is equal to a mathematical integer. round Round to the nearest integer. Examples: round(−2.5) = −2, round(-0.1) = 0, round(0.1) = 0, round(2.5) = 3 abs Absolute value (distance from zero) of a value or expression sign Sign (+1 or −1) of a value or expression Constants pi The number π (3.14159265...) e Euler's number (2.71828...), the base for the natural logarithm
