differential equations 1

q/convert each second order ode into a first order system using u=y,v=y~.solve the sysyem by eigenvalues and eigenvectors.

1)y“+25y=0

2)y“+3y`+2y=0

 

-each sysyem above graph:

a)the solution in the(u,v)plane with u(0)=1,v(0)=0

b)the function y(t) and y`(t) with y(0)=1,y`(0)=0
