This article shows how to display a graph of a function.
Lets say we want to display the graph of function f: y = 1 / x
First type the function in the main window the same way, as if you were evaluating expressions. Write only the right side of the equation. In this case, write only 1/x
.
Now go to main menu and select Tools/Graph of function… You can also use the shortcut button (circled in the image above).
The graph should now be displayed.
Note that the function must always contain a changing variable called x. If the function doesn't contain a variable named x, it will be considered constant.
If the function contains other variables (f.i.: a / x + b
), you have to enter their values the same way, as if you were evaluating an expression.
