Please inserte this to the second equation.
Hi
In few hours I got an exam in Differential equations
1 really need help with these to differential equation systems (I am not sure how to solve them). Please help ,me !!!!!!!!!!!!!!!!!
1)
x'+2x+3y=0
3x+y'+2y=2*e^(2t) , x=x(t), y=y(t)
2)
y1'= -2*y1-4*y2+1+4x
y2'= -y1+y2+(3/2)x^2
Thank you in advance for any help !!!!!!!
