- 1`#We are going to draw a graph
- 1`#of the rational function:
- 1`#@y=/Ø1±≤x+1±@
- 1`#We click the icon to open
- 1`&graphs of functions& window
- 102`The information about what to do now is
- 102`displayed below the title of the window
- 2`Following this hint, we write the formula for the value of the function.
- 3`To create a fraction we use the &/& key.
- 4`Next we move cursor to the numerator
- 4`and denominator and enter their values.
- 5`When finished, we press &ENTER&
- 6`Now we should write the co-ordinates
- 6`of some points on the hyperbola.
- 7`In the first column of the table we write:
- 7` the condition defining the domain - in the cell marked $"xπ"$...
- 7` the value which $"y"$ can never take - in the cell marked $"yπ"$...
- 8`Next points must belong to the curve.
- 9`We press the &Insert& button
- 9`to add a new column of the table.
- 9`Look at the position of the mouse.
- 10`Having introduced all the points,
- 10`we press &ENTER&.
- 11`Now we should click on a column of the table
- 11`to select a point...
- 12`and mark the point in the co-ordinate diagram.
- 12`We just place the mouse pointer at the point and click.
- 13`#In the same way we mark all of the points.
- 13`#The hints below the title of the window
- 13`#remind us what to do.
- 14`When the points are marked, the graph appears automatically.
- 100`#We show how to use 2xy to draw graphs of functions.
- 100``#"The presentation proceeds automatically."`
- 101`#In a moment the &Examples& window will appear.
- 101`You can watch the same presentation again,
- 101`#or load the next example,
- 101`#or close the window and solve your own problem.
