6. (2 pts) Consider the following initial value problem: y' = (t + y)?y2 + sin(yº) + yety, y(0) = 0. This initial value problem satisfies the existence and uniqueness theorem criteria using interval (-0, 0) for both thet and y variables, and hence has a unique solutoin. Find this unique solution. Hint: None of the techniques we've learned for explicitly solving will work. Instead, try plugging the initial condition into the differential equation and think about what that tells...

Ignore crossed out questions, thanks 3. Consider the initial value problem y(0) 0-105z(t Clearly, the solution to the system is y(t) e and(t) e-10t. Suppose we tried solving the system using forward Euler. This would give us with to- 0, y(to) 1, and z(to) 1. 2.10-5 c. In general, why would you expect forward Euler to require smaller time-steps than backward Euler? 3.
