Question
Needed to be solved D,E and F correctly in 30 minutes
Please don't copy from Chegg
So the workflow for Part 1 is basically.
1. Determine if there's any undefined areas in the ODE
2. State a rectangle where the ivp exists, but the rectangle doesn't cover any undefined areas.
3.Then you differentiate f(x,y) partially with respect to y
4.and if the function is not continuous where the IVP is then there isn't a solution and if the partial derivative isn't continuous where the IVP is then there isn't a unique solution... you have to state that
Transcribed Image Text:State a region in the x-y-plane, where the hypotheses of Picard's theorem (namely: continuity of f(x, y)
and Of(x, y)/ay) are satisfied and that contains the initial point (ro, yo). Thus, Picard's theorem allows
you to conclude that there exists a unique solution through each given initial point in this region.
