i had a problem in macsyma doing the following and wondered if anyone had any ideas about it.
i solved the following ode using ode diff(y,x)=-y+sin(x*x) and got a long involved expression involving the complex error function. i set the initial condition y=0 when x=0 using ic1. i then tried to plot by selecting the expression and pasting it into plot(<pasted expression>, x, 0, 2*%pi) when i hit return, i got the error: error in generic function. this is using windows. first: does anybody have any ideas about how to graph this? second: can i simplify this to remove the complex error function? thanks, dan stanger
