Hello Everybody I am very new to Maple and have a problem that I need help to. I have an equation and a plot in Maple that I need outputted to Excel for plotting in Excel. Is there any way to output the relevant x-y coordinates to a data file so that I can plot in Excel or can I directly output the x-y data straight into excel? Here is an example of the last few lines of Maple code. What lines of code should I add to this to get what I want? > t := .15; > r1 := 5; > sys := {diff(f1(x), x, x)-f1(x)+f2(x) = 0, diff(f2(x), x, x)-2*f2(x)+f1(x)+f3(x) = 0, diff(f3(x), x, x)-2*f3(x)+f4(x)+f2(x) = 0, diff(f4(x), x, x)+f3(x)-f4(x) = 0}; > sol := dsolve(sys, [f1, f2, f3, f4]); > s4 := proc (x) options operator, arrow; C1+C4*exp(-sqrt(2)*x)+C6*exp(-sqrt(2-sqrt(2))*x)+C8*exp(-sqrt(2+sqrt(2))*x) end proc; > s2 := proc (x) options operator, arrow; C1-C4*exp(-sqrt(2)*x)+C6*exp(-sqrt(2-sqrt(2))*x)-C6*exp(-sqrt(2-sqrt(2))*x)*sqrt(2)+C8*exp(-sqrt(2+sqrt(2))*x)+C8*exp(-sqrt(2+sqrt(2))*x)*sqrt(2) end proc; > s1 := proc (x) options operator, arrow; C1+C4*exp(-sqrt(2)*x)-C6*exp(-sqrt(2-sqrt(2))*x)-C8*exp(-sqrt(2+sqrt(2))*x) end proc; > s3 := proc (x) options operator, arrow; C1-C4*exp(-sqrt(2)*x)-C6*exp(-sqrt(2-sqrt(2))*x)+C6*exp(-sqrt(2-sqrt(2))*x)*sqrt(2)-C8*exp(-sqrt(2+sqrt(2))*x)-C8*exp(-sqrt(2+sqrt(2))*x)*sqrt(2) end proc; > solve({s1(0) = 0, s2(0) = 0, s3(0) = 0, s4(0) = (4*r1+6*t)/(r1+3*t)}, {C1, C4, C6, C8}); {C4 = 0.9587155962, C1 = 0.9587155962, C8 = 0.2808012969, C6 = 1.636629896} > C1 := .9587155962; C6 := 1.636629896; C8 := .2808012969; C4 := .9587155962; > plot([s1(x), s2(x), s3(x), s4(x)], x = 0 .. 10, legend = ["s1", "s2", "s3", "s4"]);
