Graph an equation

Model an equation on a graph and vary the equation parameters.

1. Click to create a new experiment.

2. Click the Graph Equation menu and select an equation to model:

   

   • y = mx + b

     Graph a linear equation.

   • y = A sin (ωx + φ) + C

     Graph a sine wave.

   • y = Ae^(-Bx) + y_o

     Graph an exponential function.

   • y = User-defined

     Create a custom function to display on a graph.

3. Change the items provided in the Calculator by double-clicking a line:

   • Line 1

     Contains the equation. If you create a new parameter in the equation, you must set a value for the parameter on another line.

   • Line 2

     Contains the min and max range of x and the number of data points displayed, using the format x={<min> .. <max>;<data points>}. For example, x={0 .. 10; 1000} represents a range of 0 to 10 displayed with 1000 data points.

   • Lines 3 and higher

     Contains the equation parameters.
