Explanation on how these solutions can be "easily" seen
Show that x1(t)=cos(t) and x2(t)=sin(t) are both solutions to the following Equation.
(d2x/dt2) + x = 0
Ok, So I just cannot understand how this can easily be seen! I cannot see it at all!
I know I haven't got any work to show you and that is wrong but I honestly do not know where to start with this.
It is in the middle of some lecture notes and all they say is "this can easily be seen"
Please Help this dummy!:'(
