Homework Statement
I'm stuck on Question #2 part A/B
Homework Equations
y'=r(1-y/k)y-h=y^2-ky+kh/r
y''=2y-k
Roots for y'= (k+/-sqrt(k^2-4kh/r))/2 Im assuming the positive root is y2
h<rk/4
[/B]
The Attempt at a Solution
on part a I'm getting the roots to be y2=(K+sqrt(k^2-4kh/r))/2 and...
#17 If you can't see the picture: Suppose that y1, y2, and y3 are solutions to a third order constant coefficient homogeneous differential equation. Suppose further that for all real t, W(y1,y2)(t)>0, but also W(y1,y2,y3)(0)=0. Then there exists c1 and c2 such that c1y1(t) + c2y2(t) =y3(t) for...
