Order:
1. y^I=y^2-3t
2. y^I+y^II=4y-t^2
3. y*y^III=5
1. First order (y^I) y^I=y^2-3t
2. Second order (y^II) y^I+y^II=4y-t^2
3. Third order (y^III) y*y^III=5
Linear or Nonlinear:
1. y^II+2y^I+y=t^2
2. ty^III+sin(t)y^I=y/(t+1)
3. y*y^II+y^III=t
4. y^4+sin(y^I)+3ty=0
1. linear y^II+2y^I+y=t^2
2. linear ty^III+sin(t)y^I=y/(t+1)
3. nonlinear y*y^II+y^III=t
4. nonlinear y^4+sin(y^I)+3ty=0
Linear is of the form Ay^n+By^(n-1)+...+Cy=D Where A,B,C,D are each something with only t variables)
Using maple/matlab what commands would you give to create a graph plotting the "slope field" (AKA Directional Field) of the equation
y^I=3sin(t)+1+y
with(plots);
fieldplot([1,3*sin(t)+1+y],t=-4..4,y=-4..4,arrows=line,fieldstrength=fixed(0.5));
