Question

Problem #1: (5 points) Determine a region of the xy-plane for which the given differential equation would have a unique solution whose graph passes through a point (20, yo) in the region.

Answer 1

it le number and a, b are Let i þla, then 7,3 Suebs that Question 5 Suppose that þ is a prime number and that in is an integer such that pln². We have to show that pln. first We prove that þú is a prime two integers such that plab, then plaorplo. froof. plab we are done, So, let us absume that pra, then p, a pa orze relatively prime, lie ged (p, a) = 1. So, there exceto two integers prtas=1 → b (bytas) = 1 bpr t (ab) 8= b þ løb = b / bor & plab -) A l (ab) & bo, 미 bby + tabs lie. È lb Hence the proof is complete let us consider the problem s. Since Þi a prime number and an is an integer þln² ie.pl Then by the above it follows that pln Now Now such that non teorem
