The function plot can be used to plot a standard user-defined mathematical function such as y=sin(x) or y=exp(-x^2/2)/sqrt(2*pi()).
The Function plot dialog box
- Functions: the dialog box allows to enter up to 6 functions. For the function y=sin(x) you just enter sin(x). To build a more complex function, click the button to call the Formula editor dialog box.
- Graph options
- X-axis: enter the range over which you want to plot the function.
- Y-axis: select the option "automatic" to let the program format the Y-axis, or you can enter the range for the Y-axis in the corresponding input fields.
