Example: xrange= -5:0.5:5; %the domain of x is from -5 up to 5 with 0.5 interval. yrange -10:1:10; %the values of y is from -10 up to 10 with 1 interval. [x,y] meshgrid(xrange,yrange); %plot the DE y' = x^2+y^2; s = x.^2+y^2; quiver (x,y,ones (size(s)),s) Exercises: Sketch the direction fields of the following differential equations 1. y'= 0.25xy² 2. y'= sin(x-y) Notes: For the ranges: For Item No.1
