I really seem to be having a lot of trouble with Maple that I don't have with Mathcad and I'm hoping you guys can show me what I"m doing wrong. the issue is that I'm trying to graph more than one curve on a grap which is very easy to do in Mathcad but not obviously so with Maple. My teacher told me to setup variables for each function and then use the display property to show the graphs and this works most of the time but then sometimes it does nothing at all but print the functions verbally. here is an example: restart; with(plots): g1 := implicitplot( 4-(x-2)^2): g2 := implicitplot( x/2 ): display( [ g1,g2 ] ); This just prints display(....) doesn't show a graph... This usually works but today isn't and I don't see what I"m doing wrong. NOTE: I have also added the ,x=0..10,y=0..7 but none of this changes anything so I didn't bother putting it here in my example: Any help would be appreciated as I'd like to learn to use Maple to do everything I do in mathcad... Thanks, glenn
