For the system of differential equations x' (t) = -x + y + 2xy y(t) = -x +2y-xy the critical point (xo, yo) with xo > 0, yo > 0 is xo = Change variables in the system by letting x(t) = xo + u(t), y(t) = yo+v(t). The system for u, u is u' = v' = Use u and u for the two functions, rather than u(t) and v(t) For the u, v system, the Jacobian matrix at the origin is A = Yo = You should note that this matrix is the same as J(xo, Yo) from the previous problem.

Help!!! Answer all clearly
For the system of differential equations
x' (t) = -x + y + 2xy
y(t) = -x + y - xy
the critical point (xo, yo) with xo > 0, yo > 0 is xo =
Change variables in the system by letting x(t) = xo + u(t), y(t) = yo + v(t). The system for u, v is
u' =
v' =
Use u and u for the two functions, rather than u(t) and v(t)
For the u, v system, the Jacobian matrix at the origin is
A =
Yo =
You should note that this matrix is the same as J(xo, Yo) from the previous problem.
