slopefield

[leonlenettoyeur]

Good morning! I just got my Prime yesterday and I'm pretty excited about it.

I was trying to put it through its paces last night and tried to make a slopefield. I followed the syntax listed in the User Guide as well as the syntax listed when you hit the "help" button. For example, I input

plotfield(x*COS(y),x=-5..5,y=-5..5)

and it outputs

segment(point(-5,5),point(-4.64285714286,-5.5065396169))segment...

where the ... indicates more points. I feel as if it's outputting the command for the segments to indicate slopes instead of plotting anything, but I'm sure it's user error. What am I missing to plot a slopefield? It would really help me out right now in my analytical mechanics course.
