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(...

Question

I need to print both the plots on the same figure but i cannot get the hold on command to work. Is there an explanation for this? Is there something wrong with my code? Its only showing the second plot.
eqn = 'Dy =y+2* cos(x)'; ini = 'y(0)=-2'; y=dsolve(eqn,ini,'x'); x1 = linspace(0,0.1,2); y1 = eval(vectorize(y...
