1.) (10pts) Consider the following differential equation: (x^2)(dy/dx)=2x(sqrt(y))+(x^3)(sqrt(y))
a)Determine whether the equation is separable (S), linear (L), autonomous (A), or non-linear (N). (An equation could be more than one of these types.)
b)Identify the region of the plane where the Chapter 1 Existence and Uniqueness Theorem guarantees a unique solution exists at an initial condition (x0, y0).
2.(12pts) Consider the IVP: y'+y=y/t , y(2) = 0
For each of the functions y1(t)and y2(t) below, decide if it is a solution of the IVP. (Answer is Yes or No, but show, or explain, briefly how you decided for each.)
(a) y1(t)=te-1
(b) y2(t)= t-2
