MAP2302 Test 1 (2 pts) 1. The auxiliary equation for the ODE y 00 + 2 y 0 + 3 y = 0 is given by: (2 pts) 2. In order to solve the equation y 0 + (sin x ) y = ( x 2 + tan x ) y - 3 , one should begin with the substitution v = ? (2 pts) 3. Given ( kye 3 x + tan y + e 3 y ) dy + (5 y 2 e 3 x + sin x ) dx = 0 , what should be the value of the constant k so that the equation is exact? (2 pts) 4. For the equation x 2 y 0 + 3 xy = sin x, x > 0 , the integrating factor is given by: (2 pts) 5. The general solution to the ODE y 00 + 7 y = 0 is given by:
