Hi Fellows:


If anyone has access to a copy of 'Differential Equations with Boundary-Value Problems (THIRD edition)' by Dennis G. Zill and Michael R. Cullen, I just need you to paste here or dictate to me on phone the following problem equations:

1. Problem no. 12 of chapter 4 review exercise.
2. Problem no. 23 of chapter 4 review exercise.

I will be very, very thankful to you.


Best Regards.

Why do you need these?
 
I needed them as part of assignment. My professor was out of country.

Thread 'Direction Fields and Isoclines'

I sketched the isoclines for $$ m=-1,0,1,2 $$. Since both $$ \frac{dy}{dx} $$ and $$ D_{y} \frac{dy}{dx} $$ are continuous on the square region R defined by $$ -4\leq x \leq 4, -4 \leq y \leq 4 $$ the existence and uniqueness theorem guarantees that if we pick a point in the interior that lies on an isocline there will be a unique differentiable function (solution) passing through that point. I understand that a solution exists but I unsure how to actually sketch it. For example, consider a...
