Hey All, I'm new here, but I'm getting a math degree in 20 days if I can finish this project, so hopefully when finals are over I'll be able to stick around. I'm also new to Maple. I have two ODEs which I can plot. I simplified them to be, well, very simple. The ones I want to use are more complicated by a wee bit. de:={diff(x(t),t)=x(t)+y(t),diff(y(t),t)=x(t)+y(t)}; ic:=[[x(0)=1,y(0)=1]]; ic := [[x(0) = 1, y(0) = 1]] Now I want to see how x(t) varies with (t), but all I can find to do is DEplot(de,{x(t),y(t)}, t=0..10, ic);which plots x against y. If I specify just one of the two functions, I get an error about the number of functions needing to be the same as the number of DEs. How can I plot x against t? Cheers! Don Lavelle
