Practice problems for Exam 1
Find the (implicit) solution to the separable equation
[dy/dx] = x2y-x2+2y-2
A pan of water with an initial temperature of 70°F is
placed in a freezer which is maintained at a constant temperature of 20°F.
10 minutes later, the water in the pan has reached a temperature of 50°F.
How long does it take for the water to reach 35°F?
Solve the initial value problem
xy¢ - 2y = x+1
y(1) = 3
From the textbook:
p.422: 1,3,4,5 (but the exam problem won't be nearly as long...)
