The teachpack provides two functions for graphing functions in the regular
|
|
(upper right) quadrant of the Cartesian plane (between 0 and 10 in both
|
|
directions):
|
|
|
|
@defproc[(graph-fun [f (-> number? number?)][color symbol?]) true]{
|
|
Draws the graph of @racket[f] with the given @racket[color].}
|
|
|
|
@defproc[(graph-line [line (-> number? number?)][color symbol?]) true]{
|
|
Draws @racket[line], a function representing a straight line, with a given
|
|
color.}
|
|
|
|
For color symbols, see @secref{draw}.
|
|
|
|
In addition, the teachpack re-exports the entire functionality of the
|
|
drawing library; see @secref{draw} for documentation.
