Unformatted text preview: (a) dy dx = e x + y , y (0) = 0. (b) y ( t )t ( y ( t )) 2 = t (general solution). 4. (8 points) Write down an integral in polar coordinates for the area of the region that lies inside the curve r = 2cos and outside the curve r = 2. 5. (6 points) Consider the diFerential equation y ( t ) = 1y 2 . ind the limiting behavior of y ( t ) (that is, what is lim t + y ( t )) if the initial condition is (a) y (0) = 0 (b) y (0) = 2. You do not need to solve the equation a clear explanation in a few words will suce. END O EXAM...
