Thank you alot

use this: ej\theta = cos \theta + j sin \theta this will help you out http://en.wikibooks.org/wiki/High_School_Mathematics_Extensions/Supplementary/Complex_Numbers

any hint on that?

thank you alot, so how to start solving this system? do i have to get the state-space representation of this system first? or what?

urgent help for Linearization Dear All, y" (t)+ y'(t)+y(t)=u2(t)-1 Linearize the system about y(t)=0, u(t)=1, for all t>= 0 can we say that this equation is already linear at the given point which will be y" (t)+ y'(t)+0=1-1 => y" (t) + y'(t)= 0 and no need for linearization.
