x=linspace(0,2) y1=cos(x) y2=x.^2 plot(x,y1) plot(x,y2) grid on

i tried these but getting only one line so how will i get intersection point

x=linspace(0,2,1000); y1=cos(x); y2=x.^2; plot(x,y1); plot(x,y2); grid on

I tried this but i need point of intersection of two curves so when i do this in matlab i get only one curve

does the output of fsolve means the graph itself?I tried doing it but didnt get it.

x_of_intersection = fsolve(@(x)cos(x)-x.^2,1); y_of_intersection = cos(x_of_intersection); text(x_of_intersection, y_of_intersection, 'LOOK HERE')

Replies are unlikely if you show no evidence of having attempted the homework or of having read the MATLAB documentation. If you've done minimal reading of the Getting Started material, you should be aware of the PLOT command and seen examples of its use.
