We have these two equations:
dx/dt = -k1 (y)
dy/dt = k2 x
k1= 10 k2= 10
These are the conditions:
x(0)= 100
y(0) = 0
I am so confused...This is what I have done so far...but is not making any sense...
x= (dy/dt) (1/k2)
Substitute in:
d2y/dt2 = -100 y
So the solution is...
cos a -sin a
sin a cos a
How do I find the eigenvalue of this rotation matrix? I did the usual way, but didn't work! Could someone tell me how to start this problem?

Is it ture that it would be zero in an adiabatic, process carried in consant temperature?
