Transcribed Image Text:ear differential equation, two functions y, and y2, and a pair
of initial conditions are given. First verify that y and yz are
solutions of the differential equation. Then find a particular
solution of the form y = cy + czy2 that satisfies the given
initial conditions. Primes denote derivatives with respect to x.
