1. The problem statement, all variables and given/known data θ12-γθ1+β=0 Show that 0<θ1<β 3. The attempt at a solution I know that for θ1=0, θ12-γθ1+β>0: Substituting, we get 02-0+β=β, which is positive. I don't know how to show that for θ1=λ, θ12-γθ1+β<0. I also don't know how to show that these results imply that there is zero between these two values. Which in turns means that 0<θ1<β.
