Hi - I want to graph an ode and the following are my commands: > restart; > with(plots); > with(DEtools); > plot1 := DEplot((diff(y(t), t, t))+6*(diff(y(t), t)) = 80*exp(2*t), {y(t)}, t = -1 .. 1, y = -1 .. 1, [[y(0) = 4], [(D(y))(0) = 3]], linecolor = ([BLUE, GREEN, BLACK]), arrows = MEDIUM); The error I get is : Error, (in DEtools/DEplot/CheckInitial) Too few initial conditions: [y(0) = 4] Can anybody tell me what I'm doing wrong? Thanks.
