Question

Please help. why is this not graph not working. I'm trying to print the graph of y'' + y' + y = 0 and y'' + y' + y = cos(x)
x = linspace(0,10,100) y = exp(-x/2)*cos((3^(1/2)*x)/2) + exp(-x/2)*sin((3^(1/2)*x)/2) y1 = exp(-x/2)*cos((3^(1/2)*x)/2) +...

Question

How do you show the negative x values on the graph?
x = linspace(0,7.999999999,8) y = exp(-x) + exp(-2*x) y1 = (exp(x)/6 + exp(-x) + exp(-2*x)) scatter(x,y,'r','filled')...

Question

How do I scatter the first plot into dots instead of the dash that it is set on?
syms y(x) x y1=dsolve(diff(y,x,2)+y==0); y2=dsolve(diff(y,x,2)+y==-cos(1.1*x)); y2=simplify(y2); h=ezplot(cos(...
